Audio Silence Remover
Detect internal silence by amplitude threshold and duration, retain edge margins, inspect intervals and export locally.
About this audio silence remover
Detect internal silence by amplitude threshold and duration, retain edge margins, inspect intervals and export locally Processes streaming audio and video buffers directly in the browser using HTML5 Media and Web Audio APIs with zero server uploads.
Audio and video decoding pipeline
The execution engine processes input tokens and applies transformations in the browser sandbox. Specifically, Decode audio locally at 48 kHz. A frame is silent only when every channel has absolute amplitude below 10^(dBFS/20); equality counts as sound. Detect runs at least the minimum duration and remove their interiors, keeping the selected margin at both ends, including leading and trailing runs. Review intervals and saved duration, then play or download PCM16 WAV.
