Local waveform tool — nothing leaves this tab
Drop in an MP3 or WAV, set a noise floor and a minimum gap length, and it splices out the dead air. Zoom into either waveform and click anywhere to play from that point. All decoding and processing happens in your browser.

Export is written as WAV (16-bit PCM), which every browser can encode without an external codec library. WAV keeps full quality — re-compress it to MP3 afterward in any editor if you need the smaller file size.
