Thank you for your suggestion. This is a very good idea to add a specified color or bookmark-like mark to a specific clip. I will seriously consider how to add this function.🎩

Hi, you can change the gain of voice and music track to make them equal. If it is a mixed file, you can separate it first and then add them as two track and adjust gain of each track.

Very sorry for the late reply, only Recording Studio support play and record, this feature in Audio Editor still has some design issue, I am working on it.

Hi, you can select the section and apply "Repeat" effect on it.
