wav_io is both an executable binary that can be run, and a library that can be used in Rust programs.

Installing the command-line executable

Assuming you have Rust/Cargo installed, run this command in a terminal:

cargo install wav_io

It will make the wav_io command available in your PATH if you"ve allowed the PATH to be modified when installing Rust. cargo uninstall wav_io uninstalls.

Adding `wav_io` library as a dependency

Run this command in a terminal, in your project"s directory:

cargo add wav_io

To add it manually, edit your project"s Cargo.toml file and add to the [dependencies] section:

wav_io = "0.1.15"

The wav_io library will be automatically available globally. Read the wav_io library documentation.

Samples

use std::f32::consts::PI;
fn main() {
    // make sine wave
    let head = wav_io::new_mono_header();
    let mut samples: Vec<f32> = vec![];
    for t in 0..head.sample_rate {
        let v = ((t as f32 / head.sample_rate as f32) * 440.0 * 2.0 * PI).sin() * 0.6;
        samples.push(v);
    }
    // write to file
    let mut file_out = std::fs::File::create("./sine.wav").unwrap();
    wav_io::write_to_file(&mut file_out, &head, &samples).unwrap();
