What actually happens to your song.
No magic-AI hand-waving. Here is the real pipeline, step by step, and what each stage is actually doing.
- 01
You give it something
Upload an audio or video file in the web app. On mobile, you can also record a live performance.
- 02
It extracts the audio
The video is stripped down to a clean audio track before anything else happens.
- 03
It listens for every note
A piano-specialist model estimates individual notes and their timing. Some recordings are harder to read than others.
- 04
It finds the harmony
Soonic estimates the key from detected notes and recognizes chord structure from the audio. Hand information is shown where available.
- 05
It explains why
The Breakdown presents musical context alongside the note and chord evidence, without turning an estimate into a certainty.
- 06
You practice with real tools
Loop the bar you can’t get yet. Slow it down to 50%. Speed back up when you have it.
See what Soonic knows — and what it does not.
Notes are detected; chords are estimates. Current chord results do not carry calibrated confidence scores, so use your ear when the mix is dense.

Not a DAW
SoonicAI doesn't edit or produce music. It's built for one thing: understanding piano performances.
