What AI Stem Separation is
AI Stem Separation is a browser service that splits audio into musical parts, such as vocals, drums, bass, guitar, piano, and other stems, or into vocal and instrumental tracks. Before processing, users choose 2-stem, 4-stem, or full 6-stem separation. The service says it runs Demucs on Replicate, using different models for 2- and 4-stem jobs versus 6-stem jobs. Audio can be uploaded as MP3, WAV, FLAC, M4A, OGG, or WEBM, or supplied through a YouTube or SoundCloud link. Spotify and TikTok imports are not supported. Users can preview stems, download selected tracks or a ZIP, and export WAV with a minute pack. Processing is charged by source audio length, rounded up per job, not by the number of stems downloaded. File size and duration allowances depend on the pack, and processed jobs remain available only during a limited retention window. There is no VST or AU plugin.
