Long pauses, breathing gaps, and dead air make recordings feel slower to listen to and take longer to edit by hand. This tool scans your audio, flags every stretch of silence past your chosen threshold, and trims it down automatically — all while your file stays on your own device the entire time.
Adjust the silence threshold, minimum duration, and padding to match your voice and recording environment, and the waveform preview updates instantly to show exactly what will be removed. Listen to the trimmed result before downloading it as MP3 or WAV.
No. Your audio file is decoded and processed entirely inside your browser using the Web Audio API. Nothing is ever uploaded to a server.
Most common formats your browser can decode, including MP3, WAV, M4A, and OGG. You can export the trimmed result as MP3 or WAV.
No hard limit, but since everything runs locally in your browser, very long files (45+ minutes) may be slow or use significant memory depending on your device.
The tool measures the volume (RMS) of your audio in small windows and flags stretches below your chosen threshold that last longer than your chosen minimum duration as silence, then removes them while keeping a small padding buffer so cuts don't sound abrupt.
Yes. Adjust the silence threshold, minimum silence duration, and padding sliders, and the waveform preview updates live to show exactly what will be cut before you commit.
