Pitch detection (YIN with sub-sample interpolation) runs in your browser and is tested within ±10 cents from low E to high E.
Private by design
The microphone signal never leaves your device. Nothing is recorded or uploaded.
Works with any input
Laptop mic, USB mic or audio interface. For electric guitars, an interface gives the cleanest signal.
