Add Silence to Audio Online

Yes! Click "Insert Silence", then click at the very start or end of the waveform. The tool automatically snaps to the edges for precise placement.

Yes! Click "Insert Silence" and then click anywhere on the waveform. You can add multiple insertions at different positions. Each insertion is shown in the waveform and in the list below.

Click at the very start of the waveform — the insertion point snaps to the beginning rather than landing a few samples in — and set the length. The gap appears in the waveform straight away and is audible in the preview, so you hear the pause before you export rather than discovering it is half a second short afterwards. The same click anywhere else drops a gap there instead, which is how a breath is added between two sentences that ran together.

No. The tool only inserts silent gaps — the original audio remains completely untouched. The quality of your recording is preserved exactly as it was.
