autopitch

A modular pitch detection library for Rust.

Lightweight, fast, and suitable for real-time audio analysis.

Features

• Zero dependencies
• Designed for real-time use (no heap allocations during detection)
• Simple PitchDetector trait for pluggable algorithms

Algorithms

Usage

use autopitch::algorithm::Autocorrelation;
use autopitch::detect::PitchDetector;

let mut detector = Autocorrelation::default();
let samples: Vec<f32> = /* your audio samples */;
let sample_rate = 44100.0;

if let Some(pitch) = detector.detect(&samples, sample_rate) {
    println!("Detected pitch: {:.2} Hz", pitch);
}
