[EN] Shortening long periods of silence

If you need to shorten the long periods of silence in an audio file automatically, you can use “sox”, the swiss army knife of audio stuff.

sox input.wav output.wav silence -l 1 0.1 1% -1 2.0 1% \
&& ffmpeg -i output.wav -codec:a libmp3lame -qscale:a 2 output.mp3
