From raw recording to tight audio in one step
Voice memos, dictations, interview recordings, and practice takes all share the same problem: the pauses are recorded too. Long gaps make files longer to listen to, larger to store, and slower to transcribe. Automatic silence removal deletes exactly those stretches and nothing else — the speech itself is untouched.
Because the processing is local, there is no upload limit dance and no privacy question: an hour-long recording processes quickly right in the browser, and the file never leaves your device.
