How relative loudness works still confuses me. There has be something very well defined about what the difference between the PCM values 1,332 and 3,318 should be, in terms of decibels produced. Or else I'm just lost. Let me know if I'm barking up the wrong tree, but I really don't think I am :-) -Patrick _______________________________________________ Openal mailing list [email protected] http://opensource.creative.com/mailman/listinfo/openal
