Processing Architecture & Calibration

音声と原稿をドロップして字幕化 All media streams are isolated locally inside your device using hardware-accelerated WebAssembly (WASM) and WebCodecs. Zero bytes of audio or video content are ever transmitted to external cloud servers.

How It Works

  1. Drop your audio or video file directly into the browser dropzone.
  2. The client-side engine executes local inference or bit-exact extraction without upload delays.
  3. Audition the 15-second realtime A/B comparison with the Dry/Wet slider.
  4. Export your pristine clean master file with 100% original video track preservation.
