In-browser mastering for AI music

Your Suno track,
finished like a record.

Drop in a track from Suno, Udio, ElevenLabs, Stable Audio or Riffusion. Shape the low end, open up the stereo image, and push it to streaming or club loudness — all processed on your own machine. Nothing leaves the browser.

Beta Pass Active: All premium manual fine-tune controls are temporarily unlocked for testing.

Tip: FLAC decoding depends on your browser (works in Chrome & Edge). WAV and MP3 work everywhere.

Built for AI music

Studio moves, no studio.

EQ

Tonal balance

Three-band shaping with a dedicated subsonic filter so the low end hits without muddying the mix.

↔

Stereo enhancement

True mid/side widening keeps the centre solid while the sides breathe. Pull it back to mono-safe in a tap.

LU

Loudness optimisation

Target streaming (-14) or push to club levels. A transparent limiter keeps the peaks in check.

≈

Reference matching

Drop in a track you love and Ondis tilts your EQ toward its tonal balance as a starting point.

◷

Instant A/B

Flip between the raw upload and the master while it plays. Trust your ears, not a meter alone.
