i created an audio file in ableton live which plays 10 seconds of audio, then
is silent for 5 seconds and so on for ~5 mins, exported as an aif
ran the ffmpeg silenceremove from your example (except i removed the :1 after
the -20dB
$ ffmpeg -i silencetest.aif -af silenceremove=0:0:0:-1:0.5:-20d

Are you sure? Output fil
I have removed the video and am getting the same results.
silenceremove is not removing silence.
ffmpeg -i ../2017-09-24T123913.mp4.done -vn -af
silenceremove=0:0:0:-1:0.5:-20dB:1 output.m4a

Try to set peak detection instead of rms.

in your first output paste you have
ffmpeg -i input.m4a -af silenceremove=1:5:-20dB output.m4a
looking at the man page the example says
Trim all silence encountered from beginning to end where there is more than 1
second of silence in audio:
silenceremove=0:0:0:-1:1:-90dB
I thought I'd extracted the video by simply using the m4a extension-
that's not the way that works and I should have noticed that. I bet
the audio has been truncated but the video remains the full length.
Let me strip out the video and try it.

well the only thing that looks odd to me is you have an h264 video stream in
your 'mpeg 4 audio' file. (.m4a)
have you tried extracting the audio or converting to uncompressed and running
the same command?

Here is silencedetect as well.

This 20 minute sample has over 18 minutes of silence according to
silencedetect. However silenceremove removes absolutely nothing.
input.m4a was 20:00.03 and output.m4a was 20:00.07.

I failed to mention, silencedetect does indeed detect silence when running
ffmpeg -i input.m4a -af silencedetect=n=-20dB:d=0.5 -f null -

I have used the following command
ffmpeg -i input.m4a -af silenceremove=0:0:0:-1:0.5:-20dB output.m4a
on a file. When I use another tool (Audacity) to truncate periods over
0.5 seconds of under -20dB volume it removes upwards of an hour from
the input file. When I run this command ffmpeg doesn
