The musician's app for stem separation, practice and mastering
Split any track into up to 27 isolated stems including vocals, drums, bass, guitar, piano, keys, winds and strings.
Slow the speed without changing pitch, transpose the key, loop sections and mute or solo your part while you play along.
Automatically detect the chords in a song and transcribe lyrics so you can learn songs faster.
Arrange, record and edit the same session with bandmates or producers in real time, right in the browser.
Turn any music library into a searchable, ML-organized sample pack.
Feed Polymath a single track, a folder, or a list of YouTube IDs and it builds a persistent local database of analyzed songs that can be searched instantly afterwards.
Demucs splits each song into beats, bass, vocals and other stems, which are then saved to a separated folder for use in your DAW.
Every track can be time-stretched and re-aligned to a shared tempo and beat grid (for example 120 BPM), so elements from different songs line up cleanly.
Polymath labels musical sections such as verse and chorus, detects key and loudness, and exposes that metadata for search and filtering.
