SUS4 Transcribe

Drop in any audio file. Get chords, tabs, and stems. Runs on-device — your audio stays private.

Audio in. Chords and tabs out.

You have a recording and you want to know what is being played. SUS4 Transcribe takes any audio file and returns the chords, the tabs, and the key parts — one per instrument where the analysis allows. The whole process runs on your device, which means it works offline and none of your audio ever leaves your phone.

Per-instrument tabs mean you are not just getting a rough chord chart — you are getting a readable guitar part, a bass line, a keyboard arrangement. Export as MIDI, as a text tab, as MusicXML, or as a PDF. If you need to learn a song from a recording, this is the fastest way to do it.

• Audio file transcription: chords, tabs, and MIDI from any recording • Per-instrument tabs: guitar, bass, keyboard, and more • Stem separation (requires downloadable model — coming soon) • Export formats: MIDI, text tab, MusicXML, PDF • Works with MP3, WAV, M4A, AAC, AIFF • Subscribe monthly, or unlock the full SUS4 suite forever: unlimited transcriptions, per-instrument tabs, all export formats

All AI processing runs on your device. Your audio never leaves your phone.
