SampLab Pro is a suite of six free audio and MIDI utilities that run locally in your browser: audio to MIDI, BPM and key finder, chord recognition, frequency band splitter, MIDI to audio and a lead sheet generator. No accounts and no paid tiers. Audio files up to 50 MB and 10 minutes are supported, and MIDI rendering handles up to 20,000 notes. It is a practical, independent toolkit for producers, DJs and students who want quick transcription, tempo detection and synthesis without uploading files.
