DESCRIPTION
sound is an audio demo for the PC speaker. It's the sound you
hear at the start of cLIeNUX guide..
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.
