behaviour behavior,
dont don't
And the last paragraph is weird. guessing "If you leave it enabled, then
this..."
--a52_drc_off
disable liba52 dynamic range compression [enabled]
If you dont specify this option, liba52 will provide the default
behaviour, which is to apply the full dynamic range compression
as specified in the A/52 stream. This basically makes the loud
sounds softer, and the soft sounds louder, so you can more eas-
ily listen to the stream in a noisy environment without disturb-
ing anyone.
If you let it enabled this this will totally disable the dynamic
range compression and provide a playback more adapted to a movie
theater or a listening room.
