yin-algorithm

A modern and easy-to-use Android library for real-time guitar tuning and chord detection straight from the device microphone. It captures audio, analyzes the frequency spectrum, and returns the detected note or chord — all with a pure Kotlin DSP core and no third-party audio libraries. First-class Jetpack Compose support is included out of the box.

Android Guitar Tuner that uses Yin Algorithm for Pitch Detection.
