By Administrator · Sunday, July 5 2026

Many times, while recording a video, long pauses between speaking, time for thinking or unintentional silent gaps are recorded. Such unnecessary parts make the video look long, slow and less attractive. If these silent parts can be easily removed, the video becomes more professional, smoother and better to watch. Keeping this need in mind, Silence Remover feature has been provided in Video Editor Hub of Tech Assistant for Blind App. This feature allows Visually Impaired users to remove long silent gaps present in the video. Fully compatible with TalkBack, this feature provides a great experience. Its most special thing is that Sliders have been provided to easily control all the important settings, so that every person can get the result as per his requirement.

##What is Silence Remover? what is Silence Remover? Silence Remover is a feature that automatically detects long silent gaps in the video and removes them. This improves the flow of the video, unnecessary pauses are eliminated and the final video looks more professional. There are three important settings available in this feature, which can be easily adjusted with the help of Sliders.

Silence Threshold (Volume)

This option determines how low a sound will be considered silence. - Keeping a low value (eg -50 dB) will only remove almost completely silent parts. - By keeping a higher value (like -40 dB or more), parts of slow breathing, light background noise or very low sound can also be removed by considering them as silence.

Minimum Silence Duration

This option determines how long the pause will be removed. For example if this is set to 0.50 Seconds, only Silent Gaps longer than 0.50 seconds will be removed.

Safety Buffer Margin

This is a very useful option, which keeps a little extra time (Gap) before and after the speech so that the words are not cut off suddenly. This makes video editing more natural and smooth.
