Speed Up M4A

2) Upload your video to Descript by dragging and dropping it into the project window.

3) Once upload has finished, head to the "Layer" option on the right-hand panel and adjust the speed of your clips under "Duration". You can drag left and right in the "Speed" and "Duration" boxes or — for more precise control — simply type in any multiplier.
