Drop in an audio file and get MIDI notes for each instrument, guitar/bass tab, and a chart of chord progressions, key, and BPM — all generated entirely inside your browser. Because nothing gets sent to an external server, it’s easy to work with copyrighted tracks locally as well.
Key Features
- Audio analysis engine: Combines MuScriptor (Kyutai & Mirelo, CC BY-NC 4.0) with Spotify’s Basic Pitch (Apache-2.0) and the ISMIR2019 LVCR (MIT) chord recognition model to detect notes, BPM, key, dynamics, and vibrato for each instrument.
- Fully local processing: Audio files are never uploaded to an external server — all analysis and conversion happens inside the browser. This makes it possible to work with copyrighted audio without sending it anywhere.
- Tab and chord chart generation: In addition to MIDI, it automatically generates guitar/bass tab and charts with chord progressions, key, and BPM.
- Real-time recording transcription: Transcribes audio in real time while recording, whether it’s audio playing on your computer or input from a microphone.
- Multilingual UI: Supports 8 languages — English, Japanese, Simplified Chinese, Korean, Spanish, French, German, and Portuguese.
- High-accuracy mode: When enabled, it re-checks the entire audio track to refine BPM, key, and chords, and optimizes note corrections and score/tab timing (disabled, it produces basic results quickly).
Pricing
Free to use, no account required. There isn’t even a pricing page (/pricing returns a 404), and the site has no login or payment flow anywhere — it’s offered as a single-function free tool (confirmed on the official site as of August 2026).
