SampLab Pro

SampLab Pro is an independent project not affiliated with the Samplab VST or samplab.com. Processing executes locally within the browser, keeping your audio private. Six free audio and MIDI utilities run locally in the browser, covering transcription, tempo detection, band splitting, and synthesis. Audio to MIDI converts recordings with Spotify Basic Pitch. The BPM and Key Finder estimates tempo and musical key. Chord Recognition estimates chord progressions. The Frequency Band Splitter filters audio into low, body, and high bands rather than isolating stems. MIDI to Audio synthesizes MIDI files in the browser. The Lead Sheet Generator turns pitch and chord estimates into draft notation. Every tool is free with no subscription. Outputs are algorithmic estimates to check by ear.
