Correction: Min distance is where the sound does not get any louder if you get closer. Max distance is where the sound does not get any softer if you get further away. Whether the sound is heard or not when over max distance is optional, and should also be a parameter if min/max distance is. In any case, most of this can all be handled by software. The only stuff the hardware really need is the volume, frequency, direction to sound source, and any additional effects (such as reverb). Application software can deal with the rest. ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
