OxiAudio 0.2.1 is a deep Opus conformance-hardening release: the CELT frame-size ceiling is raised from 80 bytes (~32 kbps) to the RFC's real 1275-byte limit (510 kbps mono) by fixing a celt_bits2pulses/celt_pulses2bits partition-scale clamp bug, CBR frames stop silently shrinking, hybrid packets are now entropy-exact, and encode_opus is RFC 6716-conformant by default. Pure Rust audio codec + DSP layer for the COOLJAPAN ecosystem.
OxiAudio is the COOLJAPAN Pure-Rust audio codec and DSP layer — decode FLAC/WAV/MP3/Vorbis/AAC/ALAC/Opus/WavPack/Musepack/MIDI and encode WAV/RF64/FLAC/AIFF/AU with no FFI, plus a full DSP toolkit (filters, dynamics, reverb, phase vocoder, pitch detection, EBU R128 loudness, MFCC/STFT). A clean, memory-safe alternative to libFLAC, libvorbis, libopus, and dr_libs — part of the NoFFI / COOLJAPAN sovereign Rust stack.
OxiFFT, the Pure Rust FFT and rustfft replacement, turns runtime panics into compile-time errors: 0.2.0 makes 2D/3D and real plans Option-returning with honest types, ships a drop-in fftw-compat API to port C code, and adds Debug and #[must_use] across every plan type. 858 tests passing.
OxiFFT 0.1.4, the Pure Rust FFT and rustfft replacement, adds a full signal-processing module — Hilbert transform, Welch PSD, cepstrum, and FFT resampling — plus mel-spectrogram and MFCC audio analysis. No C, no Fortran, no FFTW.
OxiFFT 0.1.0 debuts — a 99% Rust port of FFTW3. Complex/real transforms, DCT/DST, multi-dimensional and batch FFTs, runtime-dispatched SIMD, and 20+ features beyond RustFFT (Sparse FFT, STFT, NUFFT, autodiff, GPU, MPI, WASM). The spectral backbone for the SciRS2 numerical stack.
