# WebASMR

Bilingual (Chinese-first) ASMR generation, running entirely in the browser.

## What works in this build

**TTS only.** Type Chinese (or English) text, pick a voice, hit 合成. The page
loads F5-TTS ONNX from `DownFlow/webasmr-f5tts`, runs the flow-matching loop and
the vocoder in a Web Worker, and plays the result. The stats block shows
wall-clock time and level, which is what we want measured on real hardware.

The DiT is the **4-step reflow-distilled, CFG-free** model (4 int4 Euler steps,
sway -1). First click downloads ~240 MB of weights (int4 DiT bundle + int4
vocoder), cached afterwards. On a machine with hardware WebGPU the DiT runs on
hand-written WGSL kernels (about 1.2 s for a short line); otherwise it falls
back to ONNX Runtime on wasm (around half a minute).

## What is not here yet

The **LLM director** (script generation, genres, radar map, voice/artist picker,
breath rings) needs the hybrid decode graph, which is still being exported.
Until then this Space measures the acoustic stack only.
