ttl@astroatc.UUCP (Tony Laundrie) (01/17/90)
Here is a brief audio program that I wrote for generating music on the SUN
SPARCstation audio device. If you make any changes or improvements, please
send them to me, ...uwvax!astroatc!ttl or ttl@astroatc.UUCP
After unwrapping and Making the executable "beep", you can play a song
by typing "beep < soundfile". Several soundfiles (dixie, growforme, suddenly,
and jingle) are included. Have fun!
# This is a shell archive. Remove anything before this line,
# then unpack it by saving it in a file and typing "sh file".
#
echo x - Makefile
sed 's/^@//' > "Makefile" <<'@//E*O*F Makefile//'
beep: beep.c
cc -O -o beep beep.c
@//E*O*F Makefile//
chmod u=rw,g=r,o=r Makefile
echo x - README
sed 's/^@//' > "README" <<'@//E*O*F README//'
For music files used with the beep program,
The first line is:
RATE (low = fast), PITCH (low = low), VOLUME (low = quiet), DECAY (0 = no decay)
Floating point numbers accepted for RATE, VOLUME, and DECAY.
All other lines represent notes and rests, as follows:
VOL BEATS NOTE WORD
VOL and BEATS must be integers.
VOL is multiplied by first line VOLUME to get note's volume (range = 0-255).
Use VOL = 0 for a rest.
BEATS is multiplied by first line RATE to get note's length (units = 1/32 sec).
Result should be an integer.
NOTE consists of an octave (0-8) concatenated with a note (a-g) concatenated
with a flat or sharp (b or #). Badly-formed notes are not detected.
The word is printed to standard output.
Words suffixed with - don't have a space automatically printed after them.
Words suffixed with \ have a newline appended.
See "growforme" for an example.
