Author: Israel Luengo Date Posted: 2005-10-26 10:19:43 Distance: The 3D sound Fx in DirectSound, use meters as meter-unit by default. If our application not use this measure unit...we don't need convert the values wich we work, to mantain this compatibility...In fact, de application will be can able to stablish a FACTOR-Distance, this is a floating point value that represents the "meters" by each distance unit... For example, if we use "foots" as distance measure, we can specify a factor of .30480006096 that's the N� of meters in a feet.... The distance stablished by default in sound FX it be "near the real world", but mostly coders, change this values for make more dramatic FX When a Listener is coming near of a sound-source, this sound-source heared more high/stronger....once reach a reasonable level or 0 value (that you remember, it's the max value for volume) or the sound-nature forced to a logical limit. The minimal distance we can stay, related to a sound-source is specially useful, when the application must balance the diferrence between absolute volume levels for different sounds....For example, a engine of an airplane have a LOUDER sound that a BEE ....but the sound must have the same ABSOLUTE VOLUME , and an application can use a minimal-distance for 100 meters for the airplane, and 2 cm for the BEE.....with this values, the airplane engine must be listened at half-volume when the listener is at 200 meters from him, but the BEE will be must have the HALF of volume when the listener is at 4 cm of the BEE.....
