+# DeepFilterNet3 — wasm-pack browser bundle
+
+Mirror of the DeepFilterNet3 WASM browser build used by [timbrica.com](https://timbrica.com)
+`/denoise` and `/audio-enhancer` tools.
+
+Created 2026-05-07 because:
+- Upstream [Rikorose/DeepFilterNet GitHub Releases](https://github.com/Rikorose/DeepFilterNet/releases) publish only native CLI/LADSPA artefacts (no wasm-bindgen browser bundle).
+- Upstream [Rikorose/DeepFilterNet3 HF repo](https://huggingface.co/Rikorose/DeepFilterNet3) returns 401 (gated).
+- A self-hosted GitHub Release (`bandidas1/timbrica-models v1-deepfilter-wasm`) was tried but GitHub release-assets do not return CORS headers, blocking cross-origin browser fetch from non-RU pages.
+
+HuggingFace serves all files with `Access-Control-Allow-Origin: *` so cross-origin
+`fetch()` and ES `import()` from browser code work without proxy.
