AI mastering for a release-ready mix.
Upload your mix and a song that sounds the way you want. AI mastering matches its loudness, tonal balance, and width, then hands back a mastered song in the format you choose.
How AI mastering works
- 01
Add your mix and a reference
To master a song with AI, upload the finished mix, then a released song whose sound you want to match.
- 02
Match the sound
AI mastering matches loudness, tonal balance, and stereo width to your reference.
- 03
Download the master
Play the mastered song in your workspace and download it in the format you picked.

Before you master a song
For cleaner AI masteringMatch the genre
Pick a reference in the same style and tempo range. Reference mastering works best when the styles agree, as a trap master will not suit an acoustic ballad.
Leave headroom
Export your mix without a limiter on the master bus, peaking around -6 dB, so AI mastering has room to shape it.
Use a clean reference
A WAV or high-bitrate file works best. Low-quality rips pass their artifacts into your mastered song.
Sign in to upload your tracks and save masters to your workspace
Same mix, three reference-matched masters
Play the unmastered mix, then the mastered song. Each master was shaped by a different reference track, so you can hear how the choice of reference changes the result.

When AI mastering finishes a mix that is almost there
Wondering how to master a song online? Find the situation closest to yours, then choose a reference that sounds the way you want your song to sound.
Independent artists
Your single is mixed and the release date is set, but next to the songs in your playlist it sounds quieter and softer.
Good reference to tryA released song in your genre that you would be happy to sit next toA mastered song that holds its own in the same playlist
Makers of AI-generated songs
The song you made with AI sounds great in the app, but it feels flat once you line it up against a commercial release. AI mastering closes that gap.
Good reference to tryA song in the same style and tempo that already has the polish you wantA finished song you can play next to anything else you own
Bedroom producers and beatmakers
You mixed on headphones and you are not sure how it will translate. A finished song to compare against takes the guesswork out.

Video creators and podcasters
The music you made for your video is much quieter than your voice-over or the clips around it, and you keep reaching for the volume knob.

The song you pick decides how your master sounds
With reference mastering, you choose the target for AI mastering. Use this table to pick a reference that fits what you want to change when you master a song.
| If this sounds like you | Pick a reference like | Why it works |
|---|---|---|
| I want it to feel like a specific release | That release, or a sibling from the same artist or era | In reference mastering, loudness, tonal balance and width are taken from the song itself, so the closer the style, the closer the mastered song. |
| My mix sounds dull or boxed in | A bright, open song in the same genre | The reference shows the tonal balance you are aiming for, so AI mastering moves your mix toward it. |
| My song sounds quiet next to others | A song from your playlist at the level you want | Matching a song you already listen to is the quickest way to hear where your loudness stands. |
| I have an acoustic or sparse song | Another acoustic song, not a loud pop track | A dense, loud reference asks too much of a quiet arrangement. Pick one with similar instruments. |
| I made the song with AI | A finished song in the same style and tempo | A polished human-made track gives AI mastering a clear target for your generated song. |
| Question | Preset mastering | Reference mastering here |
|---|---|---|
| Who chooses the target sound | The tool, from a few built-in styles | You, with any song you like |
| What the target is | A generic profile for the genre | The loudness, tonal balance and width of one real song |
| Hearing the difference | Compare to your own unmastered mix | Compare to your mix and to the song you matched it to |
What AI mastering can do
- AI mastering brings the loudness closer to your reference
- Evens out the tonal balance so nothing sticks out
- Adjusts the stereo width to match
- Gives you the file in the format you pick, up to lossless WAV or FLAC
What happens in the mix, not the master
- Fix a mix where an instrument is too loud or missing. Go back to the mix for that.
- Master a song from single stems. Upload the full stereo mix for AI mastering.
- Bring back dynamics already squashed by a limiter. Export your mix with room to spare.
Master your song with AI in three steps
- 01
Bring your mix
Upload the full stereo mix you want to master, or pick a song you already made in My Music.
- 02
Choose a reference
Add a song that sounds the way you want yours to sound. Then pick WAV, FLAC or another output format.
- 03
Compare and keep it
Play the AI-mastered song next to your original. When the mastered song sounds right, download it. If not, try another reference and master the song again.
What to bring, and the format to take home
Two songs are enough to start: your mix and a reference. Then choose the file type that fits where the master is going.
| Input | What it does | Range |
|---|---|---|
| Your mix | The full stereo mix you want to master. Upload a file, or pick a song from My Music. | Up to 8 minutes and 50 MB |
| Reference track | The song whose sound you want. It has to be a different song from your mix. | Up to 8 minutes and 50 MB |
| File types | Common audio files from your DAW, phone or recorder. | MP3, WAV, FLAC, OGG, WEBM, M4A |
| Track title | Name the master so versions are easy to tell apart. Optional. | Defaults to your file name |
- WAV
Lossless. The default, and the best choice for sending to a distributor.
- FLAC
Lossless in a smaller file. Good for archiving your masters.
- MP3
Small and plays everywhere. Handy for sharing a quick preview.
- AAC
Compact files that suit phones and video projects.
- OGG
Open format, used by some games and web players.
- WEBM
Audio for web video and browser playback.
Each master uses 10 credits. If a master fails, the credits come back.
