Problems with pitch compensation

[Pularo]

When I try to speed up a video with audio by e.g 1.3x with the pitch compensation enabled, the audio quality suffers by a slightly robotic reverb. Does anyone else have this problem? Is there a way within Shotcut to make it sound natural?

Problem with pitch-compensation for sped up vids

Last I used shotcut was around september of 2020. It was fine, pitch compensation sort of worked. I now try to edit a video, speed a clip by 1.2, pitch compensation makes everything sound like it’s doubled, while cutting off all of the high end frequencies and demolishing percussive peaks. A flat, washed out echoing sound. Anything happen to that function over the past couple of months? Kind of sad given I rely completely on this function for the kind of videos I do.

While we have made improvements in this recently, I would say that the pitch compensation still has some echo when used on pure voice audio. For music or background sounds it works really well.

The library we use is called “Rubberband”. There is a demo application here that you can use to see how the library works for your specific audio:
