With Descript's tagging feature, you can easily identify and label ranges of non-speech audio in your clips.
In the event that you need to remove/disassociate a tag from a portion of your audio, switch to Correct Text mode.
Double click on the tag to highlight it in blue, then delete the tag. You will see that the audio is preserved in your timeline.
In the event that there is some text that needs to be restored to the audio, you can now add it back in using Correct Text mode.
