The audio engineering world, that's where; been like that many years. 
Surprised you didn't know it.

[the rest omitted because it was irrelevant]

Pad can mean-
1) to reduce (audio) "put a 20db pad on that input"
2) to add filler material (writing and other places) "let's pad that out to 
10 minutes"
3) an electronic contact surface ""solder the red wire to pad #2"
4) a place to put something "launch pad"
5) a "pad of paper"
and a bunch of others (look 'em up, you might learn something).


In the case of ffmpeg _filters_, it looks like #3 is closest as a point of 
interconnection but #2 could apply to 'pad' and 'apad' although IMHO 'fill' 
would be a better term.
