Rust port of Apple's open source ALAC library.
This crate works with Cargo and is on crates.io.
```rust use alac_encoder::{AlacEncoder, FormatDescription};
// Specify the input format as signed 16-bit raw PCM, 44100 Hz & 2 channels
let input_format = FormatDescription::pcm::
// Specify the output format as 44100 Hz ALAC with a frame size of 4096 & 2 channels let output_format = FormatDescription::alac(44100.0, 4096, 2);
// Initialize the encoder let mut encoder = AlacEncoder::new(&output_format);
// Allocate a buffer for the encoder to write chunks to. let mut output = vec![0u8; outputformat.maxpacket_size()];
// Get a hold of the source data, e.g. from a file let pcm = fs::read("foobar.pcm").unwrap();
// Iterate over chunks from the input for chunk in pcm.chunks(framesize as usize * channels as usize * 2) { // Feed the current chunk to the encoder let size = encoder.encode(&inputformat, &chunk, &mut output);
// Here you can do whatever you want with the result: Vec::from(&output[0..size]); } ```
