Free AI auto mixing and auto mastering

Finish the track instead of fighting the mix.

Upload stems or a finished song, pick the sound you are after, and hear a version you can compare in minutes.

Reference styles Processed stems 24-bit WAV Private uploads
Two core workflows

Built for the moment between demo and release.

You should not have to build a whole plugin chain just to hear where the song could go. Moozix handles the balance, the style, the master, and the exports in one place.

Auto mix your stems

For separate vocals, drums, bass, guitars, keys, and more. Moozix balances the parts first, then masters the result.

  • Stem-aware levels, tone, and dynamics
  • Built-in and custom reference styles
  • Processed stems for DAW revisions

Auto master your song

For stereo mixes that already feel close. Upload one file and get the louder, cleaner version to check before release or review.

  • Reference-based mastering direction
  • 24-bit WAV and MP3 master exports
  • Fast results from a single stereo mix
Stem automixing

Mastering plugins still can't save a bad mix.

Mastering is the last pass. If the vocal is buried or the drums are fighting the bass, a limiter will not fix the whole problem. Starting with stems gives Moozix room to balance the parts before the master.

Moozix Auto Mix Stems upload interface
01

Upload stems

Add separate tracks or start from a song that can be split into stems.

02

Choose a reference style

Use a built-in style or create your own target from a reference track.

03

Export the finished audio

Keep the WAV master, MP3 preview, premaster mix, and processed stems.

Reference control

Reference styles make the mix intentional.

Reference styles keep the result from drifting. Choose a built-in style or save one from a song you trust, then use that direction again on future mixes and masters.

Save a reusable sonic direction.

Create a custom style once, then apply it across future Auto Mix Stems and Auto Master sessions.

Give the mix a target.

Give Moozix a real target for brightness, low end, punch, and loudness.

Keep releases consistent.

Use the same reference style when you want multiple songs to feel like they belong together.

Auto mastering

Final polish without changing the workflow.

If the mix already works, master the stereo file. If you started with stems, master that result. Either way, you can keep the versions you need.

24-bit WAV master

High-resolution export for distribution, archives, and final delivery.

Release

MP3 preview

Fast review copy for headphones, collaborators, and mobile checks.

Review

Processed stems

Stems printed with the balance and tone from the Moozix mix.

Revise

Premaster mix

A clean checkpoint when you want to compare the mix and master separately.

Compare
Have stems?

Auto mix your stems.

Best when the song still needs balance between vocals, drums, bass, and instruments.

Have a stereo mix?

Auto master your song.

Best when the mix is finished and only needs the final mastering pass.

Only have one file?

Split a full song first.

Upload one finished track and Moozix can separate it into stems before starting a new mix.

Before you upload

Clear enough for a first visit. Serious enough for a release.

Do I need stems?

Stems give Moozix the most control. If you only have a finished stereo mix, use Auto Master a Song.

Is this only mastering?

No. If you upload stems, Moozix can balance the parts before mastering, so it can fix more than loudness.

Can I keep editing afterward?

Yes. Pro exports include processed stems you can bring into your own DAW for revisions, alternate versions, and final production work.

Is my music private?

Moozix says uploaded audio is private and is not used to train models.

Built for finishing songs

Auto mix the stems. Auto master the song.

Start free and use Moozix for the two jobs that matter most: automatic stem mixing and automatic mastering.
