Bug ID: 487976
Summary: Glitchy audio when playing it forward/reverse at 2X or
faster

Version: 24.05.0

OS: Microsoft Windows
Status: REPORTED

Video showing playback differences on Kdenlive and Windows Media Player
Playing audio in Kdenlive at speeds higher than 2X now produces crackling or
sharp noises that makes it hard to concentrate on dialogue if there is any in
the material. This is my use case: I go fast forward in a video to find the
interesting part of a speech and cut it in shorter clips. Listening to the
material now is very distracting with all the crackles.
Attached on this report is a video showing how the audio sounds like on
Kdenlive at 2X-3X, and how it sounds on Windows Media Player at 2X.
STEPS TO REPRODUCE
1. Have a random video with dialogue or just download an MP3 for free from
pixabay[.]com/music/
2. Insert the file on the timeline and press "L" on the keyboard until Kdenlive
starts to play it at 2X speed or faster
3.
OBSERVED RESULT
The audio is very crackly at higher speeds, similiar to noises caused by
interference.
EXPECTED RESULT
The audio should be cleaner, without the crackle and maintain the pitch.
