5500            One fourth of the Mac sampling rate (rarely seen).

11 k            Either 11025, a quarter of the CD sampling rate,
		or half the Mac sampling rate (perhaps the most
		popular rate on the Mac).
22 k            Either 22050, half the CD sampling rate, or the Mac
		rate; the latter is precisely 22254.545454545454 but
		usually misquoted as 22000.

Mac and PC ".snd"
files are completely described by these parameters:
      -t raw -b -u -r 11000
(or -r 22000 or -r 7333 or -r 5500; 11000 seems to be the most common rate).

It is usually easy to distinguish 8-bit signed formats from unsigned
by looking at the beginning of the data with 'od -b <file | head';
since most sounds start with a little bit of silence containing small
amounts of background noise, the signed formats will have an abundance
of bytes with values 0376, 0377, 0, 1, 2, while the unsigned formats
will have 0176, 0177, 0200, 0201, 0202 instead.  (Using "od -c" will
also show any headers that are tacked in front of the file.)
