We need to trim silence from mp3 files and since we're already using ffmpeg to perform some conversions, we prefer to use it to do the trimming too.
Is this possible? I can't find any reference about using ffmpeg to trim silence.
Thanks.

Here is an example:
$ ffmpeg -hide_banner -i the_4_hour_work_week.wma -af silenceremove=0:0:0:-1:5:-25dB the_4_hour_work_week.mp3
0:0:0:-1:5:-25dB
means start_periods:start_duration:start_threshold:stop_periods:stop_duration:stop_threshold
. So it will search for 5s of silence less than -25dB.
By the way, dB is case sensitive. Really. dB is the abbreviation for Decibel.
This will reencode the file? – Vitaly Zdanevich – 2018-11-11T15:20:21.287
