DESCRIPTION
sound is an audio demo for the PC speaker. It's the sound you
hear when cLIeNUX boots, if you hear a sound.
MODIFYING
cLIeNUX Core should have the sourcecode of sound in /source/C.
The sourcecode for sound provides a pitch table for 636 tone per octave
music. 636-tone is a superset of the 12 tone and 53 tone systems of equal
temperment. 53 tone and 636 tone are types of "microtonal scales".
sound uses Linux-specific escape codes similar to the vt100 escape
codes to control cursor movement on the console. sound is rather
large for what it does because it uses a constant string for each pitch,
of which it has 5100, for simplicity and due to the console escape-code
interface.
SEE ALSO
see console_codes, /configure/profile sets the beep frequency with an
echo -e, and there's a kernel patch available to emulate a soundcard with
the PC speaker.
