The questions we get asked most, answered up front
One WAV, AIFF, FLAC or MP3 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.
