How it works
How AI mastering works
1STEP 1
Upload your track
Drop in your finished mix — MP3, WAV, FLAC or M4A. It stays private and is auto-deleted from storage after 30 days.
2STEP 2
Add a reference song
Pick a professionally mastered song with the sound you want. The AI analyzes its loudness, EQ balance, stereo width and dynamics.
3STEP 3
Get your master in seconds
The engine matches your track to the reference and delivers a release-ready master — download as WAV or MP3, and A/B it against the original.
Reference mastering
Master with a reference track
Instead of a one-size-fits-all preset, this AI mastering engine works toward a real target: a song you choose. That keeps the result musical — loud where it should be, and true to the sound you're going for.
Match any reference
Upload any professionally mastered song as the target. The engine measures its RMS loudness, frequency balance, peak profile and stereo width, then matches your track to it — the same reference-matching approach audio engineers recommend for automatic mastering.
Streaming-ready loudness
Get competitive loudness without crushing your mix. The limiter keeps peaks safe for Spotify, Apple Music and YouTube, and you can switch it off to keep headroom for your own final chain.
Free online mastering, no downloads
No plugins, no DAW, nothing to install — everything runs in the browser. Start free with monthly credits and master a track in the time it takes to play it.
A/B compare and export
Flip between the original and the master instantly to hear exactly what changed. Export as WAV 16-bit for release, WAV 24-bit for further processing, or MP3 320 for quick sharing.
Who it's for
Made for everyone shipping music
From bedroom producers to beatmakers and creators — get a release-ready master without a studio, a plugin chain, or a mastering budget.
02
Bedroom producers
You mixed it in an untreated room on headphones. Reference mastering gives you the final polish and translation a treated studio would — loud, balanced, and true on every speaker.
03
Beatmakers
A whole catalog of beats to ship, all needing the same competitive loudness. Master each toward the same reference and keep your sound consistent across every drop.
04
Content creators
Clean, consistent, loud-enough audio for videos, reels, streams and podcasts — no audio engineer required. Match a reference once and every export sits at the same level.
FAQ
AI mastering, answered
For most releases, yes — especially reference-based mastering. In an independent 472-listener double-blind test of mastering services, the open reference-matching engine this tool builds on ranked third overall and first among automatic tools, ahead of several paid services. Because it masters toward a real song you choose rather than a generic preset, results stay musical instead of over-compressed.
You can start for free. Every account includes free monthly credits, and each mastered version costs a small amount of credits — try one reference or several to compare, and you only pay for the versions you generate. Paid plans add bigger credit pools for heavier use.
Mastering is the final polish on a finished mix: it balances the overall EQ, controls dynamics, sets competitive loudness, and makes the track translate well across speakers, headphones and streaming platforms. It's the step between your mix and a release-ready file.
Mixing balances the individual tracks inside a song — vocals, drums, instruments — while mastering treats the finished stereo mix as a whole. This tool does mastering: upload your completed mix, not separate stems. If your mix itself needs work, fix the balance first and then master.
Yes — that's exactly how this works. Upload any professionally mastered song you want your track to sound like, and the engine matches your track's loudness, tone and stereo image to it. Choosing a reference in a similar genre and instrumentation gives the best results.
