Free audio tools

Split or clean up audio for free

Use when the user wants stems (vocals and instrumental), an acapella or karaoke instrumental, the lead vocal apart from the backing vocals, or noise or reverb removed. Each tool includes its own 10 free minutes per rolling 24 hours; no account needed. Returns a one-time upload URL: PUT the file bytes to it, then poll links.status.
