about

nx_audio_bark.nx -- dog BARK + GROWL via SOURCE-FILTER synthesis, COMPOSED from the canonical engine (operator 2026-06-24: dedup must ABSORB capabilities + keep the most s-class). The formant source-filter (pitched glottal pulse train -> driven formant-resonator bandpasses) is the NEW capability this organ keeps. DEDUP: cosine now comes from nx_audio_osc.osc_cos_s (one cosine), and the growl rasp uses nx_audio_sfx.sfx_noise (xorshift -- the engine's good noise, replacing this organ's old inferior LCG). 48kHz, peak-normalized no-clip, lossless PCM. First-iteration timbre -- tune by ear. license_tier: ORIGINAL expect_exit: 0
