SOMETHING
SOUNDS WRONG.
Start with what you're actually hearing. Then work backward toward the cause.
Change one thing. Listen to what happens. Use that to decide what to try next.
A lot of this exists because I screwed something up, went looking for an answer, and wrote down what I learned. Some of it comes from other producers, engineers, musicians, and DIY weirdos I've met along the way. Use your ears, test things for yourself, and don't change a setting just because this page told you to.
What's going wrong?

VOCALS
What's wrong with the vocal?
VOCALS / LEVEL
What kind of level problem are you hearing?
TRY THIS FIRST
Adjust the vocal level.
If the vocal is consistently too loud or too quiet, start with the simplest fix: change the fader level.
Compression is not a substitute for simply putting the vocal at the right overall level.
TRY THIS FIRST
Try volume automation.
If entire lines or sections move noticeably forward and backward, automation gives you direct control over those changes.
Bring louder sections down and quieter sections up. Then listen again before adding more processing.
TRY THIS FIRST
Fix the problem words directly.
If only a few words or phrases jump out or disappear, you may not need to process the entire vocal more heavily.
Try clip gain or volume automation on those specific areas.
VOCALS / BURIED
Does the vocal sound loud enough by itself, but disappear when the rest of the mix plays?
CHECK FOR MASKING
Something else may be competing with the vocal.
Instead of immediately turning the vocal up, listen for instruments occupying a similar range.
Guitars, keys, cymbals, and other midrange-heavy sounds can make a vocal difficult to hear even when the vocal itself is loud enough.
START SIMPLE
Bring the vocal up.
If the vocal is simply too quiet, moving the fader may be all it needs.
Don't add compression, saturation, or EQ just to solve a basic level problem.
VOCALS / HARSH
When does the harshness happen?
FIND THE SOURCE
Figure out where the harshness lives.
Sweep a narrow EQ band temporarily to help identify the frequency range that is bothering you.
Once you find it, return the EQ to neutral and try a small, broad cut rather than leaving a giant surgical notch.
TARGET THE MOMENTS
Don't process the entire vocal for a few bad words.
If the harshness only appears occasionally, try automation or dynamic EQ on those specific moments.
A permanent EQ cut may make the rest of the vocal unnecessarily dull.
CHECK THE RECORDING
The louder performance may be changing the tone.
Check whether the microphone, preamp, interface, or recorded track is clipping when the singer gets louder.
If the recording itself is clean, dynamic EQ or automation can help control harsh moments without darkening the entire vocal.
VOCALS / MUDDY
Does the vocal sound muddy by itself, or only when everything else is playing?
CHECK THE SOURCE FIRST
Listen for excessive low-mid energy.
Microphone placement, proximity effect, the room, or the microphone itself may be contributing to the problem.
If you're still recording, try changing the microphone position before reaching for EQ.
CHECK THE REST OF THE MIX
The vocal may not be the actual problem.
Guitars, keys, bass, room microphones, and effects can accumulate energy in the same area.
Bypass or lower competing elements one at a time and see whether the vocal suddenly becomes clearer.
VOCALS / THIN
Are you still able to change the recording?
FIX IT AT THE SOURCE
Try changing the microphone position first.
Moving closer to many directional microphones can increase low-frequency response, while changing distance and angle can significantly alter the tone.
Try small position changes and listen before changing equipment or adding processing.
CHECK WHAT'S MISSING
Don't immediately boost a pile of low end.
First check for aggressive high-pass filtering, previous EQ cuts, phase issues with layered vocals, or processing that has made the vocal overly bright.
If the vocal still needs more body, try a gentle tonal adjustment rather than a dramatic boost.
VOCALS / SIBILANCE
Is the problem mostly S, SH, T, or similar consonants?
CONTROL THE SIBILANCE
Try a de-esser.
A de-esser reduces the vocal when excessive energy appears in the sibilant frequency range.
Set it so the distracting consonants become controlled without making the singer sound dull or unnatural.
THIS MAY NOT BE SIBILANCE
Go back to the harshness branch.
If the entire vocal sounds bright or painful rather than only the consonants jumping out, the issue is probably broader than sibilance.
Check microphone tone, EQ, saturation, distortion, and the upper-mid or high-frequency balance.
DRUMS
What's wrong with the drums?
DRUMS / KICK
What seems wrong with the kick?
CHECK THE SOURCE
Make sure you're starting with the sound you actually want.
If you're still recording, listen to the drum itself before trying to fix everything with EQ or compression.
Tuning, damping, the beater, microphone choice, and microphone position can all change the kick substantially.
CHECK THE REST OF THE MIX
Something may be covering it up.
If the kick sounds good alone but disappears when everything plays, don't assume the kick itself needs more processing.
Listen especially to the bass and other low-frequency-heavy parts. Try lowering competing elements temporarily and see whether the kick becomes easier to hear.
CHECK PHASE / POLARITY
Make sure the sources are helping each other.
Two microphones on the same drum capture the sound at slightly different times. When combined, some frequencies can reinforce while others cancel.
Listen to each source alone, then together. If the combined sound suddenly loses weight or punch, investigate the relationship between the tracks.
DRUMS / SNARE
What seems wrong with the snare?
CHECK THE SOURCE
Start with the drum and microphone.
If you're still recording, check the tuning, damping, microphone position, and the sound of the snare in the room before reaching for processing.
Moving the microphone changes how much shell, head, attack, and surrounding kit it captures.
CHECK FOR MASKING
The snare may be competing with the rest of the arrangement.
If it works in solo but disappears in context, temporarily lower guitars, vocals, cymbals, or other competing elements and listen again.
You may find that making room around the snare works better than continually making the snare louder or brighter.
CHECK PHASE / POLARITY
Check how the two snare microphones combine.
A microphone above the snare and one below it capture opposite movements of the drumheads and can interact differently when combined.
Listen to the top mic, then the bottom mic, then both together. If the combined snare becomes noticeably thinner or loses impact, check their relationship.
DRUMS / MUDDY OR BOOMY
Where does the problem seem to be coming from?
ISOLATE THE SOURCE
Find which drum is contributing the buildup.
Listen to the close mics one at a time and look for excessive resonance or low-mid buildup.
If you're still recording, tuning, damping, and microphone position may solve more than EQ will.
LISTEN TO THE ROOM
The microphones may be capturing something you don't want.
Overheads and room microphones capture much more than individual drums. The room itself, cymbals, low-frequency buildup, and microphone placement can all affect what you're hearing.
Temporarily lower those microphones and listen to what changes. If the muddiness clears up, you've isolated part of the problem.
CHECK THE COMBINATION
The problem may only appear when everything adds together.
Several drum microphones can each sound fine alone while contributing too much of the same frequency range when combined.
Build the kit back up one microphone at a time and listen for the point where the unwanted buildup appears.
DRUMS / CYMBALS
Where are the harsh cymbals coming from?
CHECK THE OVERHEAD BALANCE
Make sure the overheads aren't simply too loud.
Before reaching for EQ, lower the overheads and listen again. Sometimes the tonal problem is really a balance problem.
If the level feels right but particular cymbal frequencies still become painful, identify the offending area before making an EQ change.
CHECK THE BLEED
The cymbals may be reaching you through several microphones.
Soloing the overheads won't tell the whole story if the snare, tom, and other microphones also contain a lot of cymbal bleed.
Listen to those microphones together and identify which ones are adding the most unwanted cymbal sound.
FIX IT BEFORE THE MIX
Change what the microphones are hearing.
If the cymbals already sound unpleasant in the raw recording, consider the cymbals themselves, how they're being played, microphone choice, microphone position, and the room.
Moving an overhead microphone or changing its angle can alter the balance of cymbals and drums before any processing is involved.
DRUMS / SMALL OR LIFELESS
What feels like it's missing?
CHECK THE BIG PICTURE
Listen beyond the close microphones.
A kit built almost entirely from close microphones can sound very direct but may not contain much sense of the space around the drums.
Listen to any overhead or room microphones you recorded and see whether bringing some of that information back helps the kit feel larger.
CHECK THE TRANSIENTS
Listen to the beginning of each hit.
The initial attack of a drum contributes heavily to how immediate and punchy it feels.
Compare the processed track with the raw recording. If the drums lost impact after compression or other processing, the processing itself may be part of the problem.
BACK UP
Turn some things off.
Bypass your drum processing and compare it with the raw tracks. Then add each processor back one at a time.
Compression, EQ, limiting, saturation, gating, and other processing can all be useful, but several small changes can also accumulate into a drum sound that has less movement than the recording you started with.
DRUMS / KIT BALANCE
What do you mean by “they don't fit together”?
LISTEN TO THE KIT
Stop mixing every microphone in isolation.
A drum recording is several microphones describing one instrument. A kick mic doesn't necessarily need to sound impressive by itself, and neither does a snare or tom mic.
Build the drum sound while listening to the microphones together. Overheads and room microphones can provide context that close mics don't have on their own.
CHECK THE MICROPHONE RELATIONSHIPS
Listen for cancellation between microphones.
Multiple microphones hear the same drum at different times and from different positions. When those signals combine, their relationship can change the tone substantially.
Add microphones one at a time and listen for a point where the kit suddenly becomes thinner, hollow, or loses low-frequency weight.
START WITH LEVEL
Rebuild the balance before adding more processing.
If the cymbals, kick, snare, or another part of the kit dominates, start by adjusting levels rather than trying to EQ the imbalance away.
Bring the microphones down and rebuild the drum balance while listening to the entire kit.
GUITAR
What's wrong with the guitar?
GUITAR / HARSH
When does it sound harsh?
CHECK THE SOURCE
Figure out whether the harshness is already in the recording.
Bypass any processing you've added and listen to the raw guitar. If the unpleasant tone is already there, start farther upstream.
If you're still recording, listen to the amp or instrument itself. Then check microphone position, microphone choice, amp settings, pedals, and anything else affecting the sound before it reaches the DAW.
CHECK THE MIX
The guitar may not be harsh by itself.
Several bright sounds playing together can make the whole mix uncomfortable even when none of them seems especially harsh in solo.
Temporarily lower or mute other guitars, cymbals, keys, or bright effects and listen for what actually changes.
CHECK THE DISTORTION
Listen to where the fizz is actually coming from.
Distortion changes the harmonic content of the guitar, so the problem may be part of the tone itself rather than something created later in the mix.
If you can still change the source, compare different gain, amp, pedal, cabinet, or microphone settings before trying to repair it later.
GUITAR / MUDDY
Is the guitar muddy alone, or only in the mix?
CHECK THE SOURCE
Find out where the excess weight is coming from.
If you're still recording, check the instrument, amp settings, microphone placement, cabinet, room, and effects before reaching for EQ.
If you're already mixing, bypass your processing and make sure you haven't created the problem yourself.
LOOK AROUND THE GUITAR
The buildup may belong to the arrangement.
Bass, additional guitars, keyboards, vocals, reverbs, and other instruments can accumulate energy in similar ranges.
Mute or lower elements one at a time and listen for when the mix becomes clearer.
GUITAR / THIN
Where did the size go?
START UPSTREAM
Check the sound before trying to manufacture body with EQ.
If you're able to record again, listen to the instrument or amplifier in the room and compare that with what the microphone is capturing.
Microphone position, microphone choice, amp settings, and the source itself can all change the apparent weight of the guitar.
BACK UP
Compare your mix to the raw track.
Bypass EQ, filtering, compression, saturation, and other processing one piece at a time.
If the body returns when something is bypassed, reconsider whether that processor or setting is helping.
CHECK THE RELATIONSHIP
Two good sounds don't always make a bigger sound.
If multiple microphones or recordings of the same performance sound full individually but thinner when combined, investigate their timing and phase relationship.
GUITAR / BURIED
Does it disappear only when everything else plays?
CHECK FOR MASKING
Find out what appears when the guitar disappears.
Instead of immediately making the guitar louder, mute or lower likely competitors one at a time.
Another guitar, keyboard, vocal, cymbal wash, or even effects may be occupying similar space.
START SIMPLE
Turn the guitar up.
If it is simply too quiet, fix the level first. You don't need an EQ trick to solve a fader problem.
GUITAR / TOO BIG
What's taking over?
START WITH LEVEL
Turn it down.
It sounds obvious because it is. If the guitar is simply dominating the balance, lower it before trying to reshape it with processing.
FIND THE CONFLICT
The guitar may be occupying more space than the arrangement needs.
Listen for where it competes with the vocal, bass, other guitars, keys, or drums.
Then decide whether the answer belongs in level, arrangement, panning, or tone.
CHECK THE EFFECTS
The guitar may not be what's taking up all that space.
Reverb and delay create additional sound around the original guitar. Temporarily mute the effects and listen again.
If the mix suddenly opens up, rebuild the effects balance from less rather than trying to EQ your way out of too much ambience.
GUITAR / MULTIPLE PARTS
What's happening when the guitars play together?
CREATE CONTRAST
Don't ask EQ to create differences that aren't there.
If you're still arranging or recording, try changing the part, register, chord voicing, instrument, pickup, amp sound, or playing style.
Two genuinely different parts are usually easier to separate than two nearly identical parts that have been heavily processed afterward.
CHECK THE ARRANGEMENT
Ask whether every guitar needs to be playing that much.
Mute one guitar at a time. If the song gets clearer without losing anything important, you may have found the simplest solution.
CHECK PHASE / TIMING
Figure out whether these are separate performances or the same source.
If multiple microphones captured the same performance, their timing and phase relationship can change the tone when combined.
If they are separate performances, small timing and tuning differences are normal and may be part of the sound rather than something that needs fixing.
BASS
What's wrong with the bass?
BASS / CAN'T HEAR IT
When does the bass disappear?
START SIMPLE
Make sure this is actually a level problem.
Bring the bass up and listen again before adding processing. If it simply needed more level, you've solved the problem.
If increasing the level creates boominess, masking, or some other problem before the bass becomes clear, you've learned that level alone probably isn't the whole issue.
CHECK FOR MASKING
Find out what makes the bass disappear.
Bring the rest of the mix back in one section at a time, or temporarily lower likely competitors.
Kick, guitars, keyboards, and other low or low-mid-heavy sounds can make the bass harder to distinguish even when its level seems reasonable.
CHECK TRANSLATION
What part of the bass sound survives on the smaller speaker?
Small playback systems may reproduce less of the deepest bass than larger speakers or headphones.
Listen to whether the recording contains enough upper harmonic, attack, or midrange information to make the bass recognizable when the deepest part of the sound isn't reproduced as strongly.
LEVEL ISN'T THE WHOLE PROBLEM
Good. Turning it up taught you something.
If the mix gets heavier or muddier but the bass still isn't easier to follow, the part you need to hear may not be the part you're making louder.
Listen for what gives the bass its definition — attack, harmonic content, note clarity, or other information above the deepest low frequencies.
BASS / TOO MUCH LOW END
Where do you hear the boominess?
CHECK THE SOURCE AND BALANCE
Find out whether the bass itself contains too much low end.
Listen to the raw track and compare it with your processed version. If the boominess was already there, look at the source. If it appeared later, inspect what you added.
Also lower the bass temporarily. A tonal problem can sometimes simply be a level problem.
QUESTION THE ROOM
Make sure you're not fixing your monitoring instead of your mix.
Low frequencies interact strongly with rooms and listening position. If the bass sounds excessive where you mix but reasonable elsewhere, your room or monitoring position may be influencing what you're hearing.
Compare the mix on headphones and other playback systems, and move around your room while listening.
DON'T FIX THE WHOLE TRACK YET
Find out why only certain notes are jumping out.
Compare the loud notes with the surrounding notes. The cause could be the performance, the instrument, the recording, processing, or what your room is emphasizing.
Listen on another playback system before assuming the problem exists in the recording itself.
BASS / MUDDY
Is the bass unclear by itself or only in context?
CHECK THE SOURCE
Listen for what is obscuring the notes.
If you're still recording, check the instrument, playing technique, pickup or DI signal, amp tone, microphone placement, and effects.
If you're already mixing, bypass processing and compare it with the raw track.
CHECK THE ARRANGEMENT
See what else is occupying the same space.
Lower guitars, keys, kick, effects, or other dense elements one at a time and listen for when the bass becomes clearer.
BASS / INCONSISTENT NOTES
What kind of inconsistency are you hearing?
CHECK THE PERFORMANCE
You may not need to change the entire bass sound.
If only a few notes are too loud or too quiet, clip gain or volume automation can address those notes directly.
Compression can also reduce dynamic variation, but first decide whether the problem is occasional or happening throughout the performance.
CHECK WHERE IT HAPPENS
Does the same thing happen outside your mixing room?
If certain notes consistently become much louder or quieter, compare them on headphones and other playback systems.
If the problem changes dramatically with your listening position, the room may be contributing.
BACK UP
Find the point where the balance changed.
Bypass your processing one piece at a time. Pay attention to compression, saturation, EQ, and anything else that responds differently to different notes.
BASS / KICK
How are the bass and kick fighting?
CHECK THE COMBINATION
Find out what each source is contributing.
Listen to the kick alone, bass alone, and then both together. Lower one at a time and pay attention to which change actually clears the buildup.
You may need a different balance or tonal relationship, but first identify which source is contributing what.
FIND WHAT IDENTIFIES THE KICK
The kick doesn't have to win only with sub-bass.
Listen to the kick's attack and character as well as its low end. Then compare what the bass is occupying at the same moment.
Level, arrangement, tone, EQ, and dynamic control can all change the relationship.
LISTEN BETWEEN THE HITS
Figure out whether this is level, masking, or dynamics.
Listen to the bass immediately before, during, and after a kick hit.
If it only becomes difficult to hear during the kick, you've narrowed the problem considerably. Now compare their levels and tonal overlap before adding processing.
GIVE THEM DIFFERENT JOBS
Decide what you want to recognize about each sound.
If the low end is powerful but everything blends into one undefined mass, listen for the characteristics that distinguish the kick from the bass.
That distinction can come from arrangement, envelope, attack, harmonic content, level, or tone — not only EQ.
BASS / DI + AMP
What happens when you combine them?
CHECK TIMING / PHASE
The two signals may not be combining the way you expect.
A DI captures the signal directly while an amplifier microphone also includes the amp, speaker, microphone, distance, and room. Those paths do not necessarily arrive with the same timing or phase relationship.
Listen to each alone and then together. If the combination loses weight or changes dramatically, investigate their relationship.
ASK WHAT EACH TRACK IS ADDING
You don't necessarily need all of both signals.
Listen to the DI and amp separately and identify what you actually like about each one.
If combining them simply adds more of the same information, try changing their balance before processing either one heavily.
GIVE EACH ONE A REASON TO EXIST
What does each track contribute?
Maybe the DI gives you definition and consistency. Maybe the amp gives you character, distortion, space, or weight. Maybe it's the opposite.
Start with one track, then slowly add the other until it contributes something useful.
FULL MIX
What's wrong with the mix?
FULL MIX / MUDDY
When did the mix become crowded?
CHECK THE ARRANGEMENT
There may simply be too much happening in the same place.
Mute instruments one at a time and listen for when the mix becomes clearer. Pay attention to parts playing similar notes, registers, rhythms, or sustained sounds at the same time.
BACK UP
Find out what made it worse.
Bypass processing in stages. Start with mix-bus processing, then buses, effects, and individual tracks.
You're looking for the point where the mix becomes clearer again.
CHECK WHAT CHANGES
What enters the arrangement when the mud appears?
Compare a clear section with a muddy section. Look for new instruments, doubled parts, effects, denser performances, or changes in level.
FULL MIX / HARSH
Can you identify where the discomfort comes from?
ISOLATE IT
Make sure you've actually found the source.
Lower or mute the suspected instrument and listen to the full mix again. If the harshness disappears with it, you've narrowed the problem.
Now check the raw recording against the processed version to find out whether the tone came from the source or the mix.
CHECK THE COMBINATION
Several reasonable sounds can add up to too much.
Cymbals, guitars, vocals, keys, distortion, and effects may all contribute energy in similar areas.
Lower groups of sounds and listen for when the mix becomes easier to hear.
CHECK WHAT YOU ADDED
Compare the processed mix with where you started.
Bypass EQ, saturation, compression, limiting, exciters, and other processing in stages.
If the mix becomes easier to listen to when something is bypassed, investigate that processor before adding another one to compensate for it.
FULL MIX / THIN
Was the mix always thin?
LOOK UPSTREAM
The mix may be reflecting the recording and arrangement.
Before trying to make everything bigger, listen to the individual sources and the arrangement.
Ask whether the performances, tones, instrumentation, and recordings actually contain the size you're expecting.
YOU MAY HAVE CLEANED TOO MUCH
Start putting things back.
Compare the current mix with an earlier rough balance or bypass processing in stages.
Pay particular attention to filters, broad EQ cuts, aggressive dynamics processing, and anything applied repeatedly across many tracks.
CHECK THE FOUNDATION
Listen to the bass and kick before changing the whole mix.
Mute everything except the low-frequency foundation and listen to its balance.
Then add the rest of the arrangement back gradually. You may discover that the low end isn't missing — it's being masked or overwhelmed.
FULL MIX / FLAT
What does “lifeless” mean here?
CHECK THE MOVEMENT
Not everything needs to stay equally loud.
Compare verses, choruses, transitions, and important moments. Look at your automation and dynamics processing.
If you've worked hard to make everything consistently audible, you may also have reduced some of the contrast that made the song move.
CHECK DEPTH
Listen to what feels near and what feels far away.
Level, ambience, tone, performance, and stereo placement all contribute to perceived depth.
If every element has similar level and ambience, the mix may have very little front-to-back contrast.
THIS MAY NOT BE A MIX PROBLEM
Listen to the arrangement before trying to automate excitement into it.
Compare sections and ask what actually changes: instrumentation, register, rhythm, density, performance, harmony, or intensity.
BACK UP
Find where the energy disappeared.
Compare against your rough mix and bypass processing in stages. Listen especially to dynamics processing on buses and the mix bus.
FULL MIX / TRANSLATION
What changes when you listen somewhere else?
QUESTION YOUR MONITORING
Compare before changing the mix.
Low-frequency reproduction varies greatly between rooms, speakers, headphones, cars, and small playback systems.
Compare several systems and look for a pattern. Don't chase every individual playback system independently.
CHECK WHAT DEFINES THE PART
Why is the vocal easy to hear on one system and difficult on another?
Compare level, masking, ambience, and the tonal information that makes the vocal understandable.
Then compare what surrounding instruments are doing on the playback system where the vocal disappears.
LOOK FOR THE PATTERN
Is the same tonal problem following the mix everywhere?
Compare several familiar playback systems and a few well-known reference recordings.
If your mix consistently sounds brighter, darker, or muddier than references across several systems, the issue is more likely to belong to the mix.
STOP CHASING SPEAKERS
Establish a monitoring reference you can trust.
Listen to several commercial recordings you know well through the same monitoring setup.
Then compare your mix at a similar listening level. You're trying to learn what your room and speakers do to recordings that you already know translate well.
FULL MIX / LEVELS
What keeps happening?
RESET THE BALANCE
Stop the fader arms race.
If every quiet instrument gets turned up, eventually everything is loud and nothing is actually clearer.
Pull things back and rebuild the balance around the most important elements of the song.
THE SONG CHANGES
Your faders are allowed to change too.
A balance that works in a sparse verse may not work when the chorus adds guitars, cymbals, vocals, or other layers.
Use automation when the correct level genuinely changes from one part of the song to another.
DECIDE WHAT MATTERS
Not everything has to be equally obvious.
Decide what the listener should notice first, what supports it, and what can sit farther back.
If every part truly needs constant attention, revisit the arrangement as well as the mix.
FULL MIX / LOUD PLAYBACK
What falls apart when you turn it up?
CHECK AT A SENSIBLE LEVEL
Louder playback changes how you perceive the mix.
Compare the problem at moderate volume rather than making decisions while listening extremely loud.
If particular instruments or frequency areas still become uncomfortable across several systems, investigate those sources specifically.
CHECK THE FOUNDATION
Find out whether the bass, kick, or room is responsible.
Lower the bass and kick independently and listen for which change actually improves the balance.
Compare another playback system too, especially if the problem is strongest in your mixing room.
COMPARE, DON'T PANIC
Some change with playback level is normal.
Human hearing does not respond to all frequencies equally at every listening level.
Make your important balance decisions at a consistent, comfortable monitoring level and use louder and quieter checks as additional information.
KEYS / SYNTH
What's wrong with the keys or synth?
KEYS / BURIED
When does it disappear?
START SIMPLE
Turn it up.
If the part is simply too quiet, fix the level before looking for a processing solution.
CHECK FOR MASKING
What arrives when the keys disappear?
Lower likely competitors one at a time. Guitars, vocals, other keyboards, and dense effects may be occupying similar space.
THE ARRANGEMENT CHANGED
The solution may only be needed in that section.
Compare the sparse section with the busy one. What instruments or layers enter when the keys disappear?
Automation, arrangement changes, different voicings, or moving a part into another register may solve the conflict without changing the sound for the entire song.
KEYS / TOO BIG
What's making the sound feel enormous?
START WITH LEVEL
Turn it down.
Don't use EQ to solve a fader problem. Lower the part until its basic relationship with the mix feels reasonable.
QUESTION THE SOUND
The preset may have been designed to sound impressive by itself.
Listen to how much low end, high end, stereo width, layering, modulation, and ambience are already built into the patch.
If you're still creating the part, try simplifying the patch before trying to carve space out of it later.
REMOVE THE SPACE
Listen to the dry sound.
Temporarily bypass reverb, delay, chorus, widening, and other spatial effects.
If the mix suddenly opens up, add those elements back only until they're contributing what you actually want.
KEYS / MUDDY
Is the sound muddy alone or only with everything else?
CHECK THE SOURCE
Start with the patch itself.
If this is a synth or software instrument, see whether you can simplify the sound at the source.
Oscillators, layers, filters, effects, voicing, and release times can all contribute to a dense sound.
CHECK THE ARRANGEMENT
Look for overlapping parts.
Compare the keys with guitars, bass, vocals, and other sustained instruments.
Try muting parts or changing octaves and voicings before assuming every conflict needs an EQ solution.
KEYS / HARSH
Where does the harshness appear?
CHECK THE PATCH
Can you fix the sound before processing it?
If the instrument is still editable, investigate its filter, oscillator balance, distortion, resonance, effects, and other tone controls.
CHECK THE COMBINATION
The keys may only be one contributor.
Temporarily lower other bright elements and listen again. Cymbals, guitars, vocals, and several synth layers can accumulate into a harsh mix even when each sounds reasonable alone.
DON'T CHANGE EVERYTHING
If only a few moments hurt, treat them like a few moments.
Determine whether a particular note, velocity, synth layer, resonance, or effect is creating the problem.
KEYS / STEREO
What happens to the stereo sound?
CHECK MONO COMPATIBILITY
Find out what disappears when left and right combine.
Some stereo patches use delay, modulation, polarity, or other differences between the left and right channels to create width.
When those channels are combined, parts of the sound can reinforce or cancel.
QUESTION THE WIDTH
Does this sound actually need the entire stereo field?
Narrow the patch temporarily and listen to what happens to the rest of the arrangement.
If vocals, guitars, or other important parts suddenly have more room, you've identified a useful tradeoff.
ISOLATE LEFT AND RIGHT
Listen to what each side actually contains.
Some stereo patches intentionally place different layers, effects, or modulation on each side.
Listen to the left and right channels separately before assuming the imbalance is accidental.
RECORDING
What's going wrong?
RECORDING / LOW SIGNAL
Where is the signal too quiet?
START AT THE SOURCE
Follow the signal from the beginning.
Make sure the source is actually producing the level you expect, then check the first device receiving it.
Confirm that you're using the appropriate input for the signal you're connecting and that any required preamp gain is being applied.
FIND WHERE THE LEVEL CHANGES
If one meter looks healthy and the next doesn't, investigate between them.
Check the signal path between the device showing a healthy level and the DAW input.
Look at routing, output level, input selection, interface settings, and the type of connection you're using.
THIS MAY BE MONITORING
Separate recording level from listening level.
If the recording meters show a healthy signal but your headphones or speakers are quiet, increasing recording gain may be solving the wrong problem.
Check your monitor path, headphone level, control-room level, software monitoring, and any devices between the DAW and your ears.
STOP ADDING GAIN FOR A SECOND
Find out why the signal started weak.
More gain raises the wanted signal, but it can also make unwanted noise in the signal path more noticeable.
Check the source level, microphone position, input type, cables, connections, and signal path before assuming the answer is simply more gain.
RECORDING / CLIPPING
Where does the distortion first appear?
FIX IT WHERE IT HAPPENS
Reduce the level at or before the clipping stage.
If the input or preamp is already clipping, lowering the track later in the DAW won't undo that distortion.
Reduce the level feeding that stage and check whether the source is arriving at the appropriate type of input.
TRACE BACKWARD
Find the last clean stage before the DAW.
Check what is feeding the converter or interface input. Look at output levels, preamp gain, routing, and the input you're using.
Pay particular attention when one device is already sending a line-level signal into another device with its own preamp.
IT MAY NOT BE DIGITAL CLIPPING
Something earlier in the chain may already be distorting.
If possible, listen or meter the signal at different points. The source itself, a pedal, amplifier, microphone, preamp, mixer, or another device may be distorting before the signal reaches the DAW.
LEAVE SOME ROOM
Check the loudest part of the actual performance.
The average level may look perfectly fine while short peaks are clipping.
Have the performer play or sing the loudest part you're expecting, then leave enough room for the occasional surprise.
RECORDING / BLEED
What is the bleed actually causing?
Hearing another source in a microphone is not automatically a problem. First figure out what the bleed is preventing you from doing.
CHANGE THE RELATIONSHIP
Work on what the microphone hears before trying to remove it later.
Listen to the wanted source and the unwanted source separately. Then experiment with their physical relationship to the microphone.
Try changing microphone distance and orientation, moving the sources farther apart, changing their relative playing levels, or using available physical separation.
LISTEN IN CONTEXT
The processing may be changing more than the source you wanted to change.
A microphone containing multiple sources does not give your processor a clean way to know which sound you care about.
Compression can make quieter bleed more noticeable. EQ changes anything in that frequency range, including the unwanted sound.
CHECK THE MICS TOGETHER
The problem may be the relationship between microphones.
The same source can reach different microphones at different times. When those signals are combined, their relationship can change the tone in ways that sound hollow, thin, comb-filtered, or just strange.
SEPARATION STARTS IN THE ROOM
Change what reaches the microphone.
Try source placement, microphone placement and orientation, distance, relative performance levels, gobos or other useful barriers, and different microphone pickup patterns when appropriate.
WORK WITH WHAT YOU HAVE
Decide whether the bleed actually needs fixing.
Listen to the full recording before attacking individual tracks. Bleed that sounds ugly in solo may disappear into the complete performance or even help the tracks feel connected.
If it really is causing a problem, experiment with editing, automation, gating or expansion, and less aggressive processing on the affected track.
RECORDING / NOISE
When does the noise appear?
ISOLATE THAT PATH
One noisy channel gives you somewhere to start.
Swap one thing at a time with a known-good equivalent: cable, microphone or source, input, and any device in between.
LOOK FOR WHAT THEY SHARE
Multiple noisy channels may have a common point.
Look for shared equipment, power, routing, interface connections, computer connections, or another common part of the signal path.
FIND THE NOISE SOURCE
More gain may simply be making existing noise easier to hear.
Check the source level and microphone placement first. Then isolate devices in the chain to determine where the unwanted sound enters.
YOU FOUND A CLUE
If connecting one device creates the noise, investigate that connection.
Try removing other connections from that device, changing the signal connection, checking its power arrangement, and substituting known-good cables where possible.
RECORDING / MULTIPLE MICS
Does each mic sound okay by itself?
COMPARE ALONE VS TOGETHER
Investigate the timing relationship between the microphones.
When multiple microphones capture the same source, differences in arrival time can change the combined frequency response.
Try moving a microphone and recording another short test. Also test polarity reversal if your equipment provides it.
FIX THE INDIVIDUAL MIC FIRST
Don't diagnose a multi-mic problem until both signals work alone.
Check that microphone's placement, orientation, input path, cable, gain, and source relationship.
CHECK MONO
Listen to what happens when left and right are combined.
A stereo recording can sound wide and exciting while hiding relationships that become obvious in mono.
RECORDING / LATENCY
Where are you hearing the delay?
CHECK THE MONITOR PATH
Find out whether you're listening through the computer.
Software monitoring requires the signal to enter the system, be processed, and return to your headphones or speakers. That trip takes time.
If your interface provides direct or hardware monitoring, compare it with software monitoring. If you're using software monitoring, investigate your audio buffer and any processing adding significant latency.
YOU MAY BE HEARING TWO PATHS
Check whether direct and software monitoring are both active.
Hearing the immediate signal plus a slightly delayed copy can sound like an echo, doubling, or strange comb filtering.
THIS IS DIFFERENT FROM MONITORING DELAY
Check whether the recorded audio itself is misplaced.
Record a simple transient test and compare the recorded event with where you expect it to appear on the timeline.
If the recorded material is consistently offset, investigate interface drivers, DAW recording-offset settings, latency compensation, and the specific monitoring/routing setup.
RECORDING / SOURCE DOESN'T MATCH
When does it stop sounding right?
MOVE THE MICROPHONE
The microphone doesn't hear from your listening position.
Before EQing the recording, move the microphone and make short comparison recordings.
Try changes in distance, angle, height, and position relative to the source.
FIND THE CHANGE
Compare stages of the signal path.
If the source sounds right at one point and wrong at another, the useful information is somewhere between those two points.
Check input type, gain, processing, routing, converters, and any hardware between the two stages.
CHECK WHAT YOU'RE LISTENING THROUGH
The recording and the playback system are different parts of the problem.
Compare headphones, monitors, and another familiar playback system if one is available.
Also check monitor routing, level controls, accidental processing, and anything inserted on the playback path.
RECORDING / DAMAGE CONTROL
What's wrong with the recording you already have?
DON'T PRETEND IT DIDN'T HAPPEN
First decide how audible the damage actually is.
Lowering the level after recording does not remove distortion that was created earlier in the signal path.
Restoration tools may reduce some audible artifacts, but don't assume they can reconstruct a clean recording perfectly.
LISTEN BEFORE CLEANING
How much does the noise matter in the actual production?
Check the recording in context before applying aggressive noise reduction. Processing that removes noise can also change the wanted sound.
DON'T SOLO YOURSELF INTO A PROBLEM
Listen to the complete performance first.
If the bleed isn't hurting the combined recording, leaving it alone may be the best move.
If it is causing a specific problem, try automation, editing, gating or expansion, and reconsider how heavily the affected track needs to be processed.
DEFINE "BAD"
Turn the reaction into something you can test.
Is it too dark? Too bright? Too roomy? Too distorted? Too distant? Too noisy? Does the performance feel wrong?
Pick the most obvious symptom first instead of adding processing until something feels better.
MAKE THE BORING DECISION
Compare fixing it with recording it again.
Consider the performance, the problem, how difficult the setup is to recreate, and how much repair the existing recording needs.
If the performance is special or impossible to reproduce, working around technical flaws may be worth it. If the performance is easily repeatable, recording a cleaner version may be the simpler solution.
