NAME - sound, a demonstration audio thingy for the console "bell"

DOCDATE 19991009

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.
