Cauldron

A lightweight implementation of popular used audio decoders and encoders in pure Rust

Features

Planned features are: - Decode and maybe Encode support for the most popular audio codecs - Providing easy to use basic functions for audio manipulation - Providing a WASM API for web

Codec Format Support Roadmap

| Format | Flag | Read | Write | |----------|--------------|-------------|-------------| | AAC | aac | - | - | | Flac | flac | Done | - | | MP3 | mp3 | InProgress | - | | PCM | pcm | - | - | | WAV | wav | Done | InProgress | | Vorbis | vorbis | - | - |

Usage

```rust use cauldron::audio::AudioSegment; use cauldron::codecs::CodecFlag;

let mut audio_segment = match AudioSegment::read("", CodecFlag::WAV) { Ok(f) => f, Err(e) => panic!("Couldn't open example file: {}", e) };

// display some audio info println!("{}", audio_segment);

let samples: Vec = audio_segment.samples().map(|r| r.unwrap()).collect(); println!("total samples {}", samples.len()); ```

• Wav Reference Document
• Flac Reference Document
• FFmpeg for some algorithm clarity and channel layout understanding
• Claxon for code structure of Input streams

Contributing

Right now project is still in very early stages, so I am not looking for any contributions, but if you see any bug or improvement in existing implementation feel free to open a issue.
