shravan (Sanskrit: hearing / perception) -- Audio codecs for the AGNOS ecosystem.

WAV and FLAC decoding/encoding, PCM sample format conversion, sinc resampling, and audio metadata tag reading. Zero dependencies on C libraries. Pure Rust with no_std support.

Features

Feature Default Description
std yes Standard library support
wav yes WAV encode/decode
flac yes FLAC decode
pcm yes PCM format conversions
resample no Windowed sinc resampler
tag no ID3v2 / Vorbis Comment tag reading
logging no tracing instrumentation

Quick start

use shravan::codec::open;
use shravan::wav;
use shravan::pcm::PcmFormat;

// Encode samples as WAV
let samples = vec![0.0f32; 44100];
let wav_bytes = wav::encode(&samples, 44100, 1, PcmFormat::I16).unwrap();

// Auto-detect and decode
let (info, decoded) = open(&wav_bytes).unwrap();
assert_eq!(info.sample_rate, 44100);

Modules

  • wav -- RIFF WAVE encoder/decoder supporting PCM 8/16/24/32-bit and IEEE float 32-bit
  • flac -- FLAC decoder with Constant, Verbatim, and Fixed subframes, Rice coding, channel decorrelation
  • pcm -- Sample format conversion (i8/i16/i24/i32/f32/f64), interleave/deinterleave
  • resample -- Windowed sinc interpolation with Draft/Good/Best quality levels
  • tag -- ID3v2 and Vorbis Comment metadata tag reading
  • codec -- Unified auto-detect interface
