#X text 9 31 The soundfiler object reads and writes floating point
arrays to binary soundfiles which may contain 2 or 3 byte fixed point
or 4 byte floating point samples in wave \, aiff \, or next formats
(no floating point aiff \, though.). The number of channels of the
soundfile need not match the number of arrays given (extras are dropped
and unsupplied channels are zeroed out.);

;
#X text 594 161 This causes all header information to be ignored. Endianness
is "l" ("little") for Intel machines or "b" ("big") for PPC Macintoshes.
You can give "n" (natural) to take the byte order your machine prefers.
