FullOn3D heeft een artikeltje gepost waarin ze de performance van een aantal 3D audio API's vergelijken. Hier een stukje:
Basically however, A3D is to Aureal, what Glide™ is to 3dfx, i.e. A3D is Aureal’s own API, whereas DirectSound3D is part of Microsft’s DirectX API which performs a similar function (they both use the same sound hardware in the same way that Glide and Direct3D use the same graphic hardware). The DirectSound API simply produces 'wave' audio without any 3D processing and the A3D2.0 API is an extension to the basic A3D API that incorporates such things as Aureal’s Wavetracing™ technology (Aureal’s implementation of Environmental Audio). Unfortunately Descent3 only supports the A3D API, not the full A3D2.0 functions of which the Vortex2 chip is capable (fancy things like Wavetracing must usually be designed into a game from ‘day one’).
