Analyze
Understands your track
Spectrum, dynamics, stereo imaging — it builds a precise picture of where your track stands.
Decide
Judges what it needs
Every track has different problems. heywavv detects them and picks the right treatment, including the metallic fizz typical of generated tracks.
Finish
Applies just enough
Nothing heavy-handed — only as much processing as the song needs, applied naturally.
Take a generated track, for example
heywavv's own algorithm picks out just the metallic sheen in the top end and clears it
The track stays as bright as before
Hear the difference
One engine that responds differently to every track,
so any genre works
Jazz
Air around the piano and brushes stays; the bass gets defined.
Hip-hop
The kick steps forward and the vocal sits firmly on the beat.
EDM
A heavier low end on the drop, without a harsh top.
Got stems? Go deeper
It analyzes each track's role and conflicts,
cleaning things up from the mix stage
Not a fixed preset
An adaptive engine
Most mastering tools run the same chain on every song
heywavv listens first — and fixes only what your track actually needs
| Typical preset mastering | ✦ heywavv | |
|---|---|---|
| Approach | Same chain every time | Analyzes first, adapts per track |
| Input | Masters the final mix only | Works from the mix or stems |
| Intensity | Fixed processing amount | Backs off when your track needs less |
| Quality | Depends on presets | Always consistent · 96kHz / 24-bit |

Before you upload
The questions we get asked most, answered up front
One WAV, AIFF, FLAC, MP3 or M4A track, or a single ZIP of stems. Stem mastering starts at PRO, and files can be up to 1GB (2GB on STUDIO).
Upload it as is. heywavv analyzes the track and masters only as much as it needs. With stems it also balances vocals, drums, bass and music separately, and the result screen tells you if this track would benefit from stems.
Only you can see your uploads and results, and nothing is used for training. Originals are deleted after 30 days and results after 90, so download your finished files.
Yes. You keep the copyright and every right to your uploads and results — releases, YouTube, ads, anything.
Yes — it's what heywavv does best. Our own algorithm picks out the metallic fizz typical of generated tracks and clears it track by track, and it also tames harsh top end. It reduces the artifacts rather than erasing them, and groove and timing stay exactly as they were.
Try one track without signing up, then 3 tracks a month as MP3 with a free account. PRO gives you 100 tracks a month as 24-bit WAV; STUDIO is unlimited with format choice up to 96kHz.
Full refund within 7 days if you haven't processed a track in that billing period. Cancel anytime and keep access until the period ends.
