What Remove Silence does
Trim silent gaps from start, end, or throughout — tighten any recording. The result is a MP3 file you download directly.
How it works
Web Audio API + AudioWorklet for low-latency DSP, ffmpeg.wasm for codec encoding, and a custom WASM SIMD path for time-stretching and pitch-shifting. The processing code runs inside the page, so your file is not uploaded to a server — you can confirm this in your browser's DevTools → Network tab.
