[FFmpeg-user] silenceremove use

[Ted Park]

The attachment in your first reply went through fine, I can see it. But it is too simple, I mean I can remove silence in it pretty well with 
% ffplay Downloads/sample.wav -af "silenceremove=start_periods=1:start_threshold=-30dB"
But I assume you’re having more trouble with the original file because there’s occasional noise in the “silence” you want to remove, and the silence isn’t just at the beginning. Something more representative of the file you’re working with would be more helpful.

I was confused by this at first since it doesn’t seem consistent with what you described before but is this the result when the sample you sent us is used with the same commands?

No output at all is weird, but did you set -loglevel $LEVEL where LEVEL is quiet, panic, fatal, error, warning, info, verbose, debug, or trace?
