Vorbis decoder written in pure Rust.
To give the decoder a try, you can do:
cargo run --example player /path/to/your/audio_file.ogg
It will then play back the audio.
If you want to know how to use this crate, look at the examples folder.
This crate has a low level API for per-packet decoding in the

Some parts were created with help from the public domain stb_vorbis decoder implementation.
The minimum required Rust version is 1.20.
Use of unsafe
The entire library uses not a single line of unsafe code.

About the history of this crate
I've started started to work on this crate in December 2015. The goal was to learn more about Rust and audio processing, while also delivering something useful to the Rust ecosystem.
I've tried not to look into the libvorbis implementation, as then I'd have to first abide the BSD license, and second as I didn't want this crate to become "just" a translation from C to Rust. Instead I wanted this crate to base on the spec only, so that I'd learn more about how vorbis worked.
The only time I did look into the libvorbis implementation was to look up the implementation of a function needed by the ogg crate (the CRC function), which is why that crate is BSD licensed, and attributes the authors. This crate however contains no code, translated or otherwise, from the libvorbis implementation.
After some time I realized that without any help of a working implementation progress would become too slow.
Therefore, I've continued to work with the public domain
stb_vorbis implementation and used some of its
code (most prominently for the imdct algorithm) to
translate it to rust. I've also used it for debugging by
comparing its outputs with mine.
Most of this crate however was created by reading the spec only.
