Room Tone Overview


Recordings made outside of professional-grade recording studios may contain varying degrees of background noise or unwanted sounds. Maybe there’s an air conditioner in the background or line-level fuzz from your recording interface.

This is known as room tone, and when it comes to editing audio, dealing with room tone can be challenging and costly to fix, requiring the use of dedicated plugins and software.

Descript's Room Tone feature uses AI to automatically detect room tone in any given recording of speech then generates a similar tone profile. Need to add more space between two sentences or paper over an edit without jarring silence? Room Tone will seamlessly fill in the gap.


Preparing your recording

It's important to note that the Room Tone feature analyzes the first 30 seconds of a recording when generating the Room Tone sound for your gap clips. In order to assure best results, we recommend recording at least 15 seconds of silence before speaking to assure that Room Tone is able to calibrate correctly.

If you're importing a pre-recorded file and would like to take advantage of Room Tone in Descript, you will want to assure that your recording does not contain music during the first 30 seconds of the track.


Using Room Tone

When enabled, Room Tone is automatically generated in the gaps between clips your project. To add a gap clip, simply click and drag a word in the Wordbar wherever you’d like to create some space. You can also right-click on the clip and select "Insert gap clip." Room Tone will take care of the rest! 



Managing Room Tone Settings

You can manage Room Tone settings / defaults on the App level, Project-level, and Track-level.
