@tebasuna: I have no idea how to do that. How do I find those points? After I find them how do I use them? @burfadel: I did exactly what you said, but didn't work. The audio length came down to 1:42:10 and still OOS. It still has the gradual delay and ends the audio 6 seconds earlier than the 16s mark. I had entered the exact length of the video(01:42:16.640), but... There's no option higher than 12 for FFT size. It gives an error on manually increasing the value.
