OPUS medium/high bit rate audio codec Arduino library for ESP32
Production-quality Rust port of the xiph/opus audio codec (fixed-point) — CELT, SILK, Opus framing, and DNN enhancement (LPCNet/FARGAN/DRED).
Pure-Go Opus codec (RFC 6716), zero cgo. A bit-exact port of libopus, differential-tested against the C reference: the decoder passes all 12 RFC conformance vectors, and the CELT encoder produces byte-identical packets.
header-only, freestanding C++23 port of the libopus 1.6.1 decoder for one stream type: Fullband CELT only stereo 48 kHz. Bit-exact with libopus, no heap, no libm, SIMD via simd<T,N>. Done with Claude code
