Klangio
AI music transcription turning audio into sheet music, tabs, and MIDI.
About
Klangio is an AI music transcription platform that converts audio into editable sheet music, guitar tabs, and MIDI files. Instead of one generic model, it offers instrument-specific apps: Piano2Notes, Guitar2Tabs, Sing2Notes, Drum2Notes, and the multi-instrument Transcription Studio, each trained on that instrument's voicings and rhythmic patterns. It handles polyphonic detection, chord voicings, and multiple simultaneous instruments.
Users can upload MP3 or WAV files, paste YouTube links, or record from the mic, then edit results in the browser and export as PDF, MIDI, MusicXML, or GuitarPro. The company reports over 1.5 million users and 10 million transcriptions. The first 20 seconds of any transcription are free with no login; full transcriptions require a subscription.
