Extractune is a web app for separating songs and videos into vocals, drums, bass, and other instrumental audio. Its free stem separation runs in the user’s browser on a phone or computer, so the source file remains on the device. The app accepts files up to 500 MB and 20 minutes long, and does not require an account or installation. Users can split a track into separate layers for practice or editing, slow playback, change pitch or key, find a song’s key and BPM, and loop sections. Other tools convert video to MP3 or WAV and create lyric videos. The transcription feature sends audio for processing, while the Pro plan’s high quality separation runs on Extractune’s servers.
