Comment (by Balling):

 Well, the reason is obvious. 44.1 kHz sampling rate has 1 102.500 FPS (40
 SPF, samples per frame). And indeed: 308720 is perfectly divided by 40,
 while 308700 is not. This is where shorten_by should be applied and it
 should remove those 20 samples. As for 10s-sine.wav​ it has 441000
 samples. That is also perfect divide. Same for sample from #4786.
