Simple buffer playback in Rust using the rodio crate

main.rs

use rodio::Sink;
use std::fs::File;
use std::io::BufReader;

fn main() {
    // Sound output
    let device = rodio::default_output_device().unwrap();
    let sink = Sink::new(&device);

    // Buffer playback
    let file_path: String = "/home/mads/testsound/plastic1.wav".to_string();
    let file = File::open(file_path).unwrap();
    let source = rodio::Decoder::new(BufReader::new(file)).unwrap();

    // Add sound to the sink
    sink.append(source);

    // Volume
    sink.set_volume(0.25);

    // Keep the sink alive until sound stops playing
    sink.sleep_until_end();
}
