PCM decoding library for embedded systems
APACHE-2.0 License
pacmog is a decoding library for the PCM file. Designed for use in playing the PCM file embedded in microcontroller firmware. Rust has an include_bytes! macro to embed the byte sequence in the program. Using it, PCM files can be embedded in firmware and used for playback. pacmog works with no_std by default.

Read a sample WAV file.
use pacmog::PcmReader;
let wav = include_bytes!("../tests/resources/Sine440Hz_1ch_48000Hz_16.wav");
let reader = PcmReader::new(wav);
let specs = reader.get_pcm_specs();
let num_samples = specs.num_samples;
let num_channels = specs.num_channels as u32;
println!("PCM info: {:?}", specs);
for sample in 0..num_samples {
for channel in 0..num_channels {
let sample_value = reader.read_sample(channel, sample).unwrap();
println!("{}", sample_value);
}
