"Pad" in audio engineering usually means "to attenuate."
"Pad that down a bit," meaning "reduce the volume."
seriously? and that question starts with top-posting and wrong quoting!
in which crazy world means padding reduce something which would be
trimming while "padding" everywhere outside your mind means the opposite
36.39 apad
Pad the end of an audio stream with silence.
This can be used together with ffmpeg -shortest to extend audio streams
to the same length as the video stream
39.181 pad
Add paddings to the input image, and place the original input at the
provided x, y coordinates.
It accepts the following parameters: width, w height, h
Specify an expression for the size of the output image with the paddings
added. If the value for width or height is 0, the corresponding input
size is used for the output.
pad, p
If set to 1, the filter will pad the last audio packet with silence, so
that it will contain the same number of samples (or roughly the same
number of samples, see frame_rate) as the previous ones. Default value is 1.
first_pts
For swr only, assume the first pts should be this value. The time unit
is 1 / sample rate. This allows for padding/trimming at the start of
stream. By default, no assumption is made about the first frame’s
expected pts, so no padding or trimming is done

Dumb ffmpeg question alert:
What is a "pad" in the context of an "input pad", an "output pad" and a
"filter pad"?
"input pad" and "output pad" are described in chapter 32:
https://www.ffmpeg.org/ffmpeg-all.html#Filtergraph-description
"filter pad"? I don't know
