Added the possibility of changing the speed of listening to a track [acceleration or slowdown]

Good morning,
I think it would be very useful if there was the possibility to speed up or slow down the playback speed of a track (live), easily with a small button for example.
This can help, for example, when editing podcasts, conferences or voice recordings and looking for a specific phrase, or if you want to listen again and modify without wasting too much time.
Using the J K L keys the recording is much too fast and impossible to understand what the person is saying.
This possibility even exists in the Audacity software (which is nevertheless very simplistic).
THANKS!
