Key & BPM Lab

Browser toolkit for detecting song key/BPM and editing audio

Webfreemiumglobal

Key & BPM Lab is a browser-based audio toolkit that detects a song's BPM, musical key, scale and Camelot code, changes pitch and tempo independently, and can remove vocals, split stems or convert melodies to MIDI with AI, alongside basic cut/arrange/export and recording tools. It's built for DJs, musicians and producers who otherwise juggle several separate single-purpose audio apps.
