Silence Remover

As soon as the file loads, each detected pause is shaded red on the waveform and listed in the Control Panel with its start, end and length. A summary shows how many gaps will be cut, how much time that removes and how long the result will be.

Click a red region to keep that pause, and it turns grey; click it again to cut it. The list works the same way, so you can review long recordings gap by gap.

The silence threshold sets how quiet audio must be to count as silent, from -70 to -10 dB. Raise it for recordings with background noise, lower it for clean studio audio. The minimum gap, from 0.05 to 3 seconds, leaves shorter pauses alone so natural rhythm survives.

Padding, from 0 to 0.5 seconds, keeps a little audio on each side of every cut so the first and last sounds of a word are not clipped. The markers on the waveform update as you move each slider.

The preview uses the same player as ToolBuddy's other audio tools, with a waveform lane per channel, a level meter, frequency bars and a spectrum. After you remove the silence, switch between Original and Result to hear the difference.

The export starts in your file's own format and quality. The audio that remains is not changed; WAV and FLAC are lossless, and compressed formats are encoded once when you save.

Silence removal works best on speech: podcasts, interviews, lectures, narration and voice notes, where pauses are clearly quieter than talking.

Music rarely has true silence, and quiet passages can fall under the threshold. For music, lower the threshold and lengthen the minimum gap, or use the Audio Trimmer to cut just the start and end.

The silence remover cuts quiet stretches and leaves everything else as it is. To reduce steady hiss or hum, run the Noise Remover first. To cut one section, use the Audio Trimmer.

To make several clips from one long recording, use the Podcast Clip Maker, and to even out the loudness of the finished file, use the Audio Normalizer.
