Windows Process Description:

The file a3d.dll is an audio 3D library for Microsoft Windows XP Service Pack 2 that was built and developed primarily to support audio 3D capabilities working in multimedia environments. It was published and manufactured by Sensaura, Ltd., which is a division of Creative Technology. The company provides sophisticated 3D audio technology for the interactive entertainment industry.

The file a3d.dll functions as a group of sound effects that attempts to broaden the stereo image produced by two loud speakers, sound enclosures or even stereo headphones. Another function of this module is to create an illusion of sound sources placed anywhere in three-dimensional areas, including behind, above or below the listener.

The module a3d.dll has several types of audio effects. These audio effects include:

•the ability to broaden the stereo image by modifying phase information;

•the capability of placing sounds outside the stereo basis;

•and a set of functions for complete 3D simulation.

The file a3d.dll performs 3D simulation as the most advanced group of 3D Audio effects. Using head related transfer functions and reverberation changes the sound on its way from the source (including reflection from the walls and floors) to the listener's ear. This can simulate a much more dynamic entertainment experience. With the file a3d.dll, there are some 3D technologies that will convert binaural recordings to stereo recordings.

In producing the file a3d.dll, Sensaura Ltd. had licensed its technology to the three major chip manufacturers (ESS Technology, Crystal Semiconductor/ Cirrus Logic and Yamaha), who at that time supplied 70% of the PC audio market worldwide.
