Resampler (audio-resample.h): Pre-compute Kaiser-windowed sinc into a polyphase filter bank (256 phases x 64 taps = 64 KB table, fits L1 cache). Hot loop becomes a dot product with linear phase interpolation -- no transcendentals at runtime. 44100->48000, 86.8s stereo: 12.37s -> 0.32s (39x) PEAQ ODG identical (zero quality regression) WAV write (wav.h, audio-io.h): Buffer all PCM16 samples then fwrite once instead of per-sample syscalls (2*T_audio calls -> 1 call). write_wav 86.8s @ 48kHz: 0.046s -> 0.011s (4.2x)
