Sound is to be generated by realtime changing the parameter of the
sound speaker. You could quite easily do a 'BEEP <frequency>' command
but in order to do high-quality sound stuff, you'll have to synchronize
sound output to a timer and play with it very fast. That's how the
'NAMCO' voice in Soul Calibur VM mini game is done.
