How to generate PCM audio with silence of given duration?

Question

Python

How to generate PCM audio with silence of given duration? Specifically pcm_s16le.
Better with a Python library or via FFMPEG, but any others will work too

Answer 1

ffmpeg -i /dev/zero -acodec pcm_s16le -ac 1 -ar 16000 output.wav
ac - number of channels
ar - frequency
i - source (may be a file)
ffmpeg -i output.wav -f segment -segment_time 3 -c copy out %03d.mp3
-segment_time -segment time in seconds
