A browser audio tool that separates six stems, detects tempo and key, and time-stretches fluctuating recordings to a chosen BPM.

Landing page captured for the 2026-10-16 issue.

For: Musicians working with live takes that drift in tempo
Worth noticing: The page names a 100→110 BPM drift fixture and reports a 104 BPM export verified to ±1.4 ms.

Field notes

The page describes a single Rubber Band R3 pass intended to preserve transients while moving audio to a tempo grid, with beats and downbeats available for manual adjustment. It names Demucs v4 for six-source separation and lists exports ranging from a baked click track to an Ableton sidecar and MIDI tempo map. The stated free tier allows two uploads and three locks monthly.
