About Audio Silencer

Professional audio silence tool with two modes: Insert Gap adds silent pauses at specific points (increases total duration), while Mute Section replaces audio with silence (keeps same duration). Perfect for presentations, audiobooks, podcasts, and music editing.

What's the difference between Insert Gap and Mute Section?

Insert Gap adds new silence at a point, making the audio longer. Mute Section replaces existing audio with silence, keeping the same total duration. Use Insert Gap for adding pauses, use Mute Section for silencing unwanted parts.

What audio formats are supported?

Input: MP3, WAV, OGG, AAC, M4A, and other common formats. Output: Keep the same format or convert to MP3, WAV, OGG, or AAC.

How do I use each mode?

In Insert Gap mode, click on the waveform to add silence points. In Mute Section mode, drag on the waveform to select regions to mute. You can resize and move regions after creating them.

Can I preview before downloading?

Yes! Use the play button to preview the original audio. After processing, you can listen to the result before downloading.

Is my audio file safe?
