JAudio

A low-level interface for working with audio files.

Note that this is a 0.x release and a currently only wave files are supported. in the future there will be support for other audioformats as well as converting fiels within the same format.

Usage

Add the following to your Cargo.toml file:

JAudio = "0.1.1"

Wave files

Currently, only wave files are implemented.

The following example reads bytes from a file, then inserts these bytes in a WaveFile struct and finally saves the file again.

use jaudio::wave_file::*;
use std::fs;

fn main() {
    // Reading a file to bytes and creating a `WaveFile` object
    // The file has 2 channels, a sample rate of 44100Hz and 16 bits per sample
    let mut bytes: Vec<u8> = WaveFile::file_to_data("audio.wav").unwrap();
    let mut wave = WaveFile::new(AudioFormat::PCM, 2, 44100, 16);
    
    // adding the audio from the file we read to wave
    wave.add_bytes(&mut bytes);
    
    // The path we want to save the file to
    let path = "file.wav";
    fs::write(path, wave.to_bytes()).unwrap();
}

Contributions

Contributions ar very welcome, as I will probably not get around to completing all audio file formats. Optimizations to code are also very welcome.
