v1.0.0 — Initial Release

Pure Go implementation of the Opus audio codec (RFC 6716), with no runtime CGO dependency.

Features

  • Encoder: Accepts 8/12/16/24/48 kHz mono/stereo input; resamples to 48 kHz; emits CELT-only fullband 20 ms packets
  • Decoder: Full CELT, SILK, and hybrid (SILK+CELT) packet decoding
    • Hybrid SILK+CELT reconstruction (time-domain sum)
    • Hybrid SILK→CELT redundancy / crossfade
    • RFC 6716 §3.2.5 code-3 multi-byte padding support
  • RFC 8251 official test vectors: 12/12 PASS (all RMSE < 0.001)
  • Entropy coder: Range encoder/decoder (internal/entcode)
  • DSP utilities: FFT, MDCT/IMDCT, windowing (internal/dsp)
  • Resampler: Opus-rate sample rate conversion (internal/resampler)
  • CI: GitHub Actions matrix (amd64 + arm64), race detector, benchmarks, fuzz targets
