- Cooley-Tukey radix-2 FFT (forward + inverse with /N normalization) - WOLA STFT/ISTFT with Hann window (nfft=2048, hop=512) - WAV16 read + WAV24 write (fixed aliasing bug in read) - Fixed in-place processing bug (separate input/output buffers) - Biquad filter (peak/shelf/reject) - Peak detector skeleton - MS encode/decode (M8 stereo) - Harness: WAV16 → STFT → WAV24 passthrough verified non-zero output Verified: burst500.wav passthrough produces output RMS=0.0678
