Why? You are not telling the whole story.
My fantasy story for you is: I work for the German secret service and
monitor telephone conversations. The VOX files contain the recordings
from side A and B respectively. Unfortunately, the technology is not
perfect. For some reason, the recording of side A is usually somewhat
slower, probably due to asynchronous processes in the background. In a
42-minute conversation, the difference _can_ be up to 20 seconds. That's
why I try to stretch the recording with the shorter duration to the
duration of the longer recording in order to get the dialog in sync.
The individual files are mono and with the merging it remains mono.
I had already tried the tempo option, but that didn't work at all.
Stretching is not worthwhile when the difference is so small. A certain
tolerance can be taken into account. However, I will make it dependent
on the length in future.
chatgpt is an ideal helper (albeit with flaws) who doesn't ask
superfluous questions and always tries to offer individual solutions and
even spreads good vibes. I can't say that your text puts me in a good
mood ;-) But thank you for taking the trouble to reply. It would have
been your chance to show that humans can still be smarter than AI :)
I'll keep experimenting with it until the result is perfect.
