Ableton Live mix analysis — find what's wrong and how to fix it

Drop a bounce from Ableton Live and Unveil tells you why it isn't sounding pro yet — loudness, dynamics, tonal balance, phase, and frequency conflicts — then gives you fixes written for Ableton Live's own stock plugins. No third-party plugins to buy — just a free account to try it.

Where Live's meters actually read

Live's track and master meters show sample peak level in dBFS, with the fader at 0 dB meaning unity gain. Internally Live mixes in floating point, so the master channel can show a level above 0 dB without anything being damaged yet. The damage happens at the output stage or at export, when a fixed-point file or a converter cannot represent the value. That is why a red master meter in Live is a warning about what will happen later, not a record of a clip that already exists.

The practical consequence is that you can fix a hot master by pulling the master fader down, and the stored result is identical to having mixed quieter, as long as nothing nonlinear (a limiter, saturator or clipper) sits before the point where you reduce. Order matters: a level problem created before a nonlinear device cannot be undone by turning down after it.

Also remember that the meter shows sample peaks, not true peaks. A master reading -0.3 dBFS can reconstruct to +0.5 dBTP or more after digital-to-analog conversion or lossy encoding. Our analyzer measures true peak with 4x oversampling for exactly this reason, and a ceiling of about -1 dBTP is the safe target.

Headroom and the group-track habit

Live encourages bussing through Group tracks, and each group has its own fader and meter. A common failure is four drum tracks each peaking at -6 dB feeding a drum group, which then peaks near 0 dB because the sum is louder than any single part. Check the group meters, not only the individual tracks.

• For a mix you will hand to a mastering engineer, aim for master peaks around -6 dBFS with no limiter on the master.
• If the master is regularly passing -3 dBFS before you have touched dynamics, lower every group by the same amount instead of dragging the master fader, so the groups still show healthy headroom.
• Use a Utility device at the end of a group chain when you need a clean trim. Its Gain control is easy to automate and it keeps your faders near their most precise range.
• Do not use the master fader as a loudness control while a Limiter sits on the master. The limiter reacts to the signal entering it, so the fader after it only changes final level, and the fader before it changes how hard the limiter works. Know which one you are moving.

The stock tools worth knowing

EQ Eight is a parametric equalizer with eight bands, per-band filter types, and an Adaptive Q option that narrows the bell as you boost more. It also has Left/Right and Mid/Side processing modes, which makes it the right tool for cutting low frequencies on the sides only. Its built-in analyzer is useful for finding where a build-up lives, but trust your ears for whether it matters.

Compressor handles most jobs: choose peak or RMS-style detection behavior, set attack and release, and use the sidechain section to duck a bass under a kick. Glue Compressor is the bus compressor, modeled on classic console style. Typical use is a ratio of 2:1 or 4:1, a slowish attack of 10 to 30 ms so transients pass, an auto or medium release, and no more than 1 to 3 dB of gain reduction on the mix bus.

Utility offers gain, width, mono, phase invert and a Bass Mono function, which folds the low end to mono below a chosen frequency. Limiter is the final-stage device with Gain, Ceiling and Release controls; the Spectrum device gives a larger frequency display than EQ Eight's analyzer, useful for checking the six tonal regions of your mix (sub, bass, low-mid, mid, hi-mid and air) at a glance.

One honest limitation: as far as we know Live's stock devices do not include a BS.1770 integrated loudness (LUFS) meter. To check against the roughly -14 LUFS Spotify and YouTube reference or the roughly -16 LUFS Apple Music reference, you will need a third-party meter plug-in or an external analysis tool.

Exporting from Live: analysis versus delivery

Open the Export Audio/Video dialog. For the rendered track, choose Master. The two controls that cause most problems are Normalize and Dither. Turn Normalize off for anything you are analyzing, because it rescales the file to peak at 0 dBFS, which destroys your headroom and misrepresents the true peak. Choose a bit depth of 24 for a mix going to mastering; dither is unnecessary at 24-bit.

For final delivery to a distributor that wants 16-bit, 44.1 kHz WAV, export at the session sample rate if possible and let the dither option do its job once, at the final bit-depth reduction. Never dither and then process the file again. Keep the sample rate the same as your project unless the destination requires otherwise, since sample-rate conversion adds another processing step.

Before exporting, look at the master Limiter if you use one. If its gain reduction meter is flickering past 6 dB on every beat, you are not leveling the track, you are flattening it. Back off the input gain and lower the ceiling to -1 dB.

Worked fix: a boomy build-up around 150 Hz

Suppose analysis shows the bass region (80 to 250 Hz) sitting about 4 dB above where comparable records sit, and the mix feels thick and slow. Do not cut the entire master; first find out which tracks are responsible.

1. Solo the Group containing bass, kick and any low pads and open EQ Eight on that group, not the master.
2. Enable one band, set it to a bell, and place it at 150 Hz with a Q of about 0.8 for a broad correction.
3. Cut 3 dB. Compare with the device turned off using a level-matched A/B, since louder always sounds better and you need to be sure the cut is actually an improvement.
4. Sweep the center frequency between 120 and 200 Hz with a 5 dB boost temporarily to confirm where the boominess sits, then return to a cut at that frequency.
5. If the cut thins the kick, switch the band to Mid/Side mode, cutting only the sides, or move the cut from the kick's group to the bass guitar or pad that actually carries the excess.
6. Re-measure the whole mix. A 3 to 4 dB cut at the source should pull the bass region back to within about 3 dB of target without any change to the other five bands.

Mistakes that are specific to Live workflows

• Leaving Normalize ticked in the export dialog after a loudness check, then wondering why the delivered file peaks at 0 dBFS and clips when encoded.
• Putting a Limiter on the master at session start as a safety net and mixing into it. The limiter hides balance problems and makes every EQ and compression decision less trustworthy.
• Judging bass by Spectrum alone. A narrow peak on a display is not necessarily audible, and a wide shelf of excess energy often is.
• Stacking several EQ Eight instances with tiny boosts instead of one clean cut. Subtractive moves almost always sound more natural.
• Forgetting that warped audio clips and returns can add level not visible on the individual track meters. Check the Return tracks' own meters and the master together.

Checklist before you bounce

After you export, measure the file again so the numbers confirm what you heard.

• Master peaks no higher than about -1 dBFS for a final, or -6 dBFS for a pre-master.
• No limiter gain reduction beyond what you chose deliberately.
• Normalize off; 24-bit for mastering, dither only on final reduction to 16-bit.
• Bass Mono or a Utility set to Mono below roughly 100 Hz on sub-heavy material.
• Compare against a reference at matched loudness for the last pass.

What you get

• A 0–100 mix score with a per-metric breakdown (LUFS, true peak, dynamic range, stereo, tonal balance).
• Time-localized frequency conflicts — the exact moment and band where elements collide.
• Step-by-step fixes using EQ Eight, Glue Compressor, and Utility — e.g. a corrective EQ Eight bell at the flagged frequency.
• Genre-aware targets so a trap bounce isn't judged against an acoustic record.
