audio_samples_io

Fast and simple audio reading and writing in Rust

Rust crate providing audio file I/O utilities and helpers.

audio_samples_io is the IO extension of the audio_samples crate. audio_samples_io builds on top of the representations provided by audio_samples to provide the functionality necessary for reading, writing and investigating audio files.

NOTE: Still under development

Currently only supports .wav files

• flac
• mp3
• aiff
• ogg
• aac

Quick start

Install via:

cargo add audio_samples_io

use std::time::Duration;

use audio_samples_io::error::AudioIOResult;
use audio_samples::{AudioSamples, sine_wave};

pub fn main() -> AudioIOResult<()> {
    // create and write a basic signal and read it back
    let sine_wave: AudioSamples<f32> =
        sine_wave::<_, f32>(440.0, Duration::from_secs_f64(10.0), 44100, 1.0);
    audio_samples_io::write("./sine_wave.wav", &sine_wave)?;

    let read_sine_wave: AudioSamples<f32> = audio_samples_io::read("./sine_wave.wav")?;
    println!("{:#}", read_sine_wave);
    println!("Duration: {:.1}s", read_sine_wave.duration_seconds::<f32>());
    Ok(())
}

Benchmarks

Checkout the benchmark summary doc for a comparison against Hound and libsndfile.

To run the benchmarks (Criterion) reading and writing.

cargo bench --bench wav_rw

I have included a small benchmark reported binary for collating benchmarks to a markdown file

cargo run --bin benchmark_reporter --features benchmark_reporting

Output files

• benchmark_report.md — Markdown summary generated by the reporter binary
• benchmark_results.csv — Detailed CSV export of benchmark rows (times in μs)
• benchmark_summary.csv — Executive summary CSV
