AI mastering
AI mastering, online
Make your AI sound more human. Upload your Suno, Udio, or AI-generated song, repair the artifacts, balance the mix, and master it for release. Hear the before and after first. Downloads need a membership.
What the AI mastering chain does
Four stages, in order, on every track. No preset guessing at your file.
01 Measure
Loudness is measured as K-weighted, gated integrated LUFS to ITU-R BS.1770, the same method the streaming platforms use when they normalise your track. Nothing is guessed from peak level.
02 Shape
Genre-aware EQ and multiband compression handle the tonal balance, then a de-harsh stage measures the 5 to 10 kHz range and cuts only what is actually there. AI exports usually need that; a live recording usually does not.
03 Level
A look-ahead limiter brings the track to the target for the platform you picked, holding true peak at -2 dBTP so nothing clips when the platform re-encodes it to AAC or MP3.
04 Compare
Original and mastered play against each other before you decide anything. Loudness is matched between them, so the louder version cannot pass itself off as the better one.
Loudness target for every platform
Choose where the track is going and the master is built to that spec.
| Platform | Integrated loudness | True peak |
|---|---|---|
| Spotify | -14 LUFS | -2 dBTP |
| Apple Music | -16 LUFS | -2 dBTP |
| YouTube | -14 LUFS | -2 dBTP |
| SoundCloud | -9 LUFS | -2 dBTP |
| TikTok | -13 LUFS | -2 dBTP |
| Amazon Music | -14 LUFS | -2 dBTP |
| Tidal | -14 LUFS | -2 dBTP |
| Dolby Atmos | -18 LUFS | -2 dBTP |
Questions about mastering online
What do I get before paying?
You can master your track and compare it against the original before paying. Downloading the finished WAV or MP3 needs a membership at EUR 4.99 a month, billed monthly, cancel any time.
When do I need an account?
Only to download. Upload a track, master it, and compare it against your original first.
Does my music get uploaded to a server?
No. Mastering runs in your browser using the Web Audio API, so the audio stays on your device. A file only leaves your machine if you choose to save a finished master to your library.
Does it work on Suno and Udio tracks?
Yes, and that is what most people bring here. The de-harsh stage is aimed at the high-frequency sheen AI generators leave on vocals and cymbals. There is a Suno-specific set of tools if a track needs repair before mastering.
What loudness should I master to?
Pick the platform and the target follows: Spotify -14 LUFS, Apple Music -16, YouTube -14, TikTok -13. Mastering far louder than the target does not make you louder on the platform. It gets turned back down, with less dynamic range left than you started with.
What formats can I export?
24-bit WAV and 320 kbps MP3, once a membership is active.
Working with AI music? There is a Suno toolkit for repair before mastering, stem separation if one element needs fixing on its own, and a reference master if you want to match a commercial track. Comparing options first? See the AI mastering tools we tested.
