Extra time added to tracks when converting m4a to mp3

[Oliver]

Converting m4a to mp3, the process throws no errors. But the resulting mp3s have extra time and size (may the double). Extra time added is silence.

SoundConverter 4.0.3
Linux Mint Debian Edition Faye

Can't reproduce, but it might depend on the exact settings.

Try to run soundconverter from a terminal in debug mode, like this:

soundconverter --debug

Then paste the log. It should, among other things, print something like:

DEBUG: converter.py, line 321, launching: 'giosrc location="file:///mnt/data/music/MPEG-4/foo/bar/qux.m4a" name=src ! decodebin name=decoder ! audiorate ! audioconvert ! audioresample ! lamemp3enc encoding-engine-quality=2 target=bitrate cbr=true bitrate=192 ! id3mux ! giosink location="file:///tmp/qux.m4a~721454~SC~"'

Please also run

sudo apt install gstreamer1.0-tools
gst-launch-1.0 --version

It seems that an extra period of silence is added before the end of the song. I have attached a screenshot of the wave.
