scripts to create floating-point and integer soundfiles

These are all older utilities to create soundfile (headers only) -- the disk-based Cmix required soundfiles to pre-exist, at least in header form, on disk for information about sampling rate, etc. The rtoutput command does not have this restriction.

all are shell scripts that bundle up options for the sfcreate command, because we used to get tired of typing all them numbers and letters back in the Olden Days

Here's what they are:

    F1: sfcreate -r 44100 -c 1 -f -t sun $1 (writes a 1-channel floating-point 44.1k soundfile header) F2: sfcreate -r 44100 -c 2 -f -t sun $1 (writes a 2-channel floating-point 44.1k soundfile header) I1: sfcreate -r 44100 -c 1 -i $1 (writes a 1-channel 16-bit integer 44.1k soundfile header) I2: sfcreate -r 44100 -c 1 -i $1 (writes a 2-channel 16-bit integer 44.1k soundfile header)
Pretty silly, huh?

Here's a Handy Fact To Know -- all of these scripts (and sfcreate itself, of course) can write a new header onto a pre-existing file without disturbing too much of the file's contents (you may lose a few bytes at the front depending on the size of the header and any pre-existing headers on the file). Ever wondered what your executable sounds like?
