Comment (by ltratt):

 The logging is very helpful, but unless I'm missing something else
 obvious, FFmpeg has no way of ''automatically applying'' the latency
 compensation as Sox and Audacity can. For example, with the noisegate, I
 have to run it, check what the latency was, and rerun it with `apad` and
 `atrim` manually (and hope that the latency hasn't changed). For backwards
 compatibility, the latency compensation almost certainly couldn't be
 applied in all cases, but (like Sox with its `-l` switch) it could be an
 option?
