pitch_detection

Usage

use pitch_detection::detector::mcleod::McLeodDetector;
use pitch_detection::detector::autocorrelation::AutocorrelationDetector;

const SAMPLE_RATE : usize = 44100;
const SIZE : usize = 1024;
const PADDING : usize = SIZE / 2;
const POWER_THRESHOLD : f64 = 5.0;
const CLARITY_THRESHOLD : f64 = 0.7;

// Signal coming from some source (microphone, generated, etc...)
let signal = vec![0.0; SIZE];
let mut detector = McLeodDetector::new(SIZE, PADDING);

let pitch = detector.get_pitch(&signal, SAMPLE_RATE, POWER_THRESHOLD, CLARITY_THRESHOLD).unwrap();

println!("Frequency: {}, Clarity: {}", pitch.frequency, pitch.clarity);
