How do I detect and remove silence from an audio recording?

Upload your audio file, set silence threshold (dB) and minimum silence duration (milliseconds), and inspect all silent regions highlighted on the waveform for 1-click removal.

Why remove silence from voice notes or podcasts?

Trimming dead air, long pauses, and breaths tightens speech pacing and cuts 10% to 30% off total recording length.

Can I customize the silence threshold?

Yes. Adjust threshold between -60 dB (very quiet room) and -30 dB (louder background noise) to fine-tune sensitivity.

Can I preview trimmed audio before exporting?

Yes. Listen to the condensed recording with instant live playback.

What formats are supported?

Supports MP3, WAV, M4A, AAC, and OGG files.

Is processing done locally?

Yes. All silence analysis executes in local browser memory.
