WebGPU runs operations on your GPU (fast when supported). WASM runs on CPU; SIMD is automatic; multithreading needs cross-origin isolation (COOP/COEP). Without COI, WASM uses 1 thread.

      
Streaming: 48-frame windows, hop 40, keep center 40. Equal-power crossfade removes seams. “Sequential” forces no overlap and starts each chunk only after the previous ended (sets crossfade to 0).
