daniel	3d0406ef64	test(pitch_shift): tighten purity f0 to 1/196 so revert-of-fadeLen_ fails; add hop guard; clamp fadeLen_ in double before int64 cast	2026-07-28 06:59:04 -04:00
daniel	436a685984	fix(pitch_shift): ratio-scale splice fade so +24st up-shifts never read stale data; normalize SOLA correlation by candidate energy; tests bracket 4x/0.5x + unity/latency asserts	2026-07-28 06:37:38 -04:00
daniel	22d7893431	fix(preserve): correlation-aligned splices replace dual-tap OLA — fixed w/2 tap offset anti-phase-cancelled crossfades (beating/partials on repitched sines); spectral-purity test added	2026-07-28 06:19:26 -04:00
daniel	1e1d6bddbb	S15/S16: Gate(AHDSR)/Trigger play modes + Varispeed/Preserve pitch engines + AD pitch envelope ... Per-zone play params on SampleData; hand-rolled pure pitch_shift OLA for Preserve (WDL drags windows.h); zone-payload v3 tail; RT-safe pre-warmed shifters + Preserve voice cap.	2026-07-27 04:16:48 -04:00
