BandLab Mastering vs Automix: How to Get Your Tracks Release-Ready

BandLab makes it easy to create music. You can record, layer tracks, collaborate with other artists and build complete songs from your phone or browser, for free. But when it comes to releasing your music, there is a gap between what BandLab produces and what listeners expect on Spotify or Apple Music.

This post covers BandLab Mastering - what it actually does, where it falls short - and how to get your tracks sounding professional and release-ready.

What is BandLab Mastering?

BandLab Mastering is a built-in mastering tool available directly inside BandLab. It is free, requires no additional software and works on your finished stereo mix. You choose a preset, apply it, and download the result.

The four free presets are Universal, Fire, Clarity and Tape. Four additional presets - Natural, Cinematic, Spatial and Punch - plus an 11-step intensity slider are available with a paid BandLab Membership.

It is a straightforward tool and for a free, built-in option it does a reasonable job of applying overall loudness treatment and basic tonal shaping to a finished track.

Where BandLab Mastering falls short

The fundamental limitation of BandLab Mastering is the same one that applies to all stereo mastering tools: it works on your finished mix as a single file, which means it cannot address problems within the mix itself.

If your vocal is sitting too low, your bass is clashing with the kick, or your low end is muddy and uncontrolled - mastering cannot fix any of that. It processes the whole stereo file with the same treatment regardless of what is happening inside it. A preset master makes everything louder and slightly brighter. It does not balance your mix.

There are a few other specific limitations worth knowing:

Stereo files only. BandLab Mastering works on your final stereo bounce. It does not accept individual stems or tracks.

Preset-based processing. The presets apply the same curve to every track regardless of genre, arrangement or what the track actually needs. There is no stem-level analysis of your specific audio.

No reference matching on the free tier. Reference track matching - where the mastering tool targets the sonic profile of a commercial release - is not available on the free BandLab presets.

What this means in practice

If your BandLab mix is well-balanced - every element sitting clearly in the right place, good frequency separation, controlled low end - BandLab Mastering will get it to a releasable loudness level and it will sound reasonable on streaming.

If your mix has problems, those problems will still be there after mastering. They will just be louder.

Most independent artists making music in BandLab are mixing their own tracks without formal training. That is not a criticism - it is just the reality of how independent music gets made. And it means the mix stage, not the mastering stage, is usually where the biggest gains are available.

How Automix approaches it differently

Automix works on your individual stems rather than your finished stereo mix. That distinction matters because it means every element can be processed separately - the vocal treated independently from the guitars, the bass and kick balanced against each other, the drums given the right relationship with the rest of the arrangement.

The result is not just a louder version of whatever you gave it. It is a mix where the relationships between elements have been addressed, followed by mastering that sets the final loudness and prepares the track for streaming.

Automix includes mastering as part of the same workflow. You upload stems, the AI mixes and masters the session, and you get a preview of the full result before paying anything. If you are happy with it, download. If not, adjust the genre, importance settings or stem categorisation and try again.

Exporting your stems from BandLab

To use Automix with your BandLab tracks you need to export your individual tracks as separate WAV files rather than bouncing the full mix.

In BandLab, go to your project and export each track individually. A few things that make a difference:

Label everything clearly before exporting - Kick, Snare, Bass, Lead Vocal, Backing Vocal and so on. This makes the categorisation step in Automix faster.

Export as WAV, not MP3. WAV retains all the audio information. MP3 discards data to reduce file size - once that information is gone, no amount of processing will bring it back.

Do not over-process before exporting. If you have stacked multiple effects on a track in BandLab, consider whether they are serving the sound or just adding clutter. Automix works best with clean stems that have not been heavily compressed or EQ'd already.

Make sure all stems start at 0:00. Every file should start at the same point in the timeline so the timing relationships are preserved in the mix.

Which option is right for you

If you have a finished stereo mix that is already well-balanced and you want a quick, free loudness treatment before releasing: BandLab Mastering does that job without requiring anything else.

If your mix has balance problems, you want more control over the result, or you want mastering that is informed by what is actually happening in your individual tracks: Automix is the right next step. The free mix download lets you hear exactly what the difference sounds like before you commit to paying.
