The versions I've seen are very messy. Maybe they don't expect anyone
to actually read it, instead probably using something else like
Audacity to record.

-b. If you specify nothing it should detect that the card is only
capable of 8-bit and make the necessary adjustments automatically.

Either signed or unsigned is default. It doesn't really matter, most

More recent versions of sox include a "rec" script, which works like
"play" for recording.

Recent versions of play will automatically do the resampling for you,
as needed. MPlayer will, also.
