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
A video or audio file, or a live recording straight from your piano in the app. YouTube links work too, for most videos.
- 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 neural model trained on real performances picks out individual notes — pitch, timing, and velocity — not just the loudest thing in the mix.
- 04
It finds the harmony
Notes get grouped into chords, the key gets detected, and left-hand notes get separated from right-hand notes.
- 05
It explains why
Chord progressions get matched against gospel harmonic patterns — turnarounds, ii-V-Is — and explained in plain language, not just labeled.
- 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.
Every chord carries its own confidence.
A clean triad is easy to hear correctly. A rootless 13th chord buried under a vocal run is not. We show you the difference instead of pretending every detection is equally certain.
What you can give it
A file
MP4, MOV, WebM, MP3, WAV, or M4A, uploaded straight from your browser.
A live recording
In the iOS and Android app only — record straight from your piano and get a breakdown on the spot.
A YouTube link
Paste it and go — no download required. Works best with clips under about 90 seconds; if a particular video won't load, uploading the file usually does the trick.
Not a DAW
SoonicAI doesn't edit or produce music. It's built for one thing: understanding piano performances.
