AI Audio Stretch for Windows

This guide helps you simply set the length of the audio, and there’s no need to cut, ripple, or add fades.

AI Audio Stretch is a useful tool to remix music automatically. It allows you to retime the audio clip easily to match the duration of the video. The beginning and end of the material remain the same in the remix, and the middle will be edited.

  •  A vlog with multiple scenes and different music clips. Music is always a solution to link clips, showing the feeling of each scene you want to present. However, the length of each clip may not be satisfied.
