If your .wav is a bit longer than the mp3 but not long enough to fill up another chunk at the end this might get discarded. Don't quote me on this, just remembering something I asked here years ago... * Scott Temby [2021-06-17 16:03]: > Hi, > > When using "sox.exe *.wav* -C 192.01 > *.mp3* norm" > I've found the output is occasionally truncated (shorter duration than the > input, but matches up to that point). > > I've tried this on a few systems, and while the fault is intermittent (not > linked to any particular input file or condition), it does repeatedly occur > (a few times in a "batch").
