sndfile.rs

A safe rust wrapper of libsndfile.
With this crate, you can reade or save audio files.

Getting Started

sndfile.rs is available on crates.io. With minimal features:

[dependencies]
sndfile = "0.0"

With ndarray supports:

[dependencies.sndfile]
version = "0.0"
features = ["ndarray_features"]

...and see the docs for how to use it.

Example

extern crate sndfile;
extern crate ndarray;

fn main() {
  use sndfile::*;
  let mut snd = sndfile::OpenOptions::ReadOnly(ReadOptions::Auto).from_path(
    "/mnt/st4t_0/tuxzz/muz/muz0/Call My Name/13.Loow.flac"
  ).unwrap();
  let data: ndarray::Array2<f32> = snd.read_all_to_ndarray().unwrap();

  let samplerate = snd.get_samplerate();
  let n_frame = snd.len().unwrap();
  let n_channels = snd.get_channels();
  let title = snd.get_tag(TagType::Title);
  println!("Loaded song `{}`:", title);
  println!("  Length: {:.2} seconds", n_frame as f64 / samplerate as f64);
  println!("  Sample rate: {} Hz", samplerate);
  println!("  Channel count: {}", n_channels);
  println!("  DC offset = {}", data.mean().unwrap());
}

/*
== Expected output ==
Loaded song `Loow`:
  Length: 277.06 seconds
  Sample rate: 44100 Hz
  Channel count: 2
  DC offset = 0.00018921464
