Online mixing and mastering
Mix and master any song in minutes.
How AI mixes a finished song
Most online mastering only polishes the finished stereo file. This tool goes one step back. It splits your song into four parts (vocals, drums, bass and the rest of the music), mixes those parts like an engineer would, then masters the result.
- 1
Split
An AI stem separator pulls the four parts out of the stereo song in your browser.
- 2
Level
Each part is measured and moved to a set balance against the vocal, so the vocal sits on top and the band supports it.
- 3
Shape each part
The vocal gets presence, air and compression; the drums get parallel compression for punch; the bass is kept centred so it stays solid on phones and in clubs.
- 4
Make room for the vocal
The music dips in the vocal's frequency range only while the singer sings, by 2 to 3.5 dB depending on the sound, then comes back.
- 5
Master
The mix is mastered with tone shaping, glue and a true-peak limiter for a safe, loud finish.

Mixing and mastering, or mastering only?
Use mixing and mastering when the vocal is buried, the bass is too loud or too weak, or the drums lack punch. Those are balance problems inside the song, and only a mix can fix them.
Use mastering only when the balance already sounds right and the song just needs to be louder, clearer and ready for Spotify. It's faster and keeps the mix exactly as it is.

Tips for the best result
Upload the highest quality you have:
WAV or FLAC beats a compressed MP3.
Leave a little headroom:
a song that already clips gives the splitter less to work with.
Try two sounds on the same song;
switching takes seconds once the song is split.
Judge the result with the before and after at a similar volume,
on earbuds and a phone speaker.

Questions.
What is the difference between mixing and mastering?
Mixing balances the parts of a song: vocals, drums, bass and music. Mastering is the final polish on the finished song: loudness, tone and a safe peak level. This page does both.
How long does it take?
Usually one to three minutes, depending on your device and song length. The first run also downloads the mixing AI once. Changing the sound afterwards takes seconds.
Does it work on Suno and Udio songs?
Yes. Upload the exported song from Suno, Udio or any AI generator, or your own recording.
Do I need stems?
No. Upload the full song and it is split into vocals, drums, bass and music for you.
Is it free?
Mixing, mastering and the before and after are free to try. Downloading the WAV needs a membership.
What files can I upload?
WAV, MP3, FLAC, M4A and more, up to 100 MB.
What can't it do?
Splitting a finished song is never perfect, so a little bleed between parts is normal, especially on dense AI mixes. The first run downloads the mixing AI once (about 170 MB). Older phones may fall back to mastering only.
