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.
Hardware-accelerated whole-slice SIMD vector primitives for Go (AVX-512, AVX2, NEON, SVE2, RVV) — zero cgo, zero dependencies, 100% portable Go fallback.
