The Audigy2 features a renovated CA0102-IAT digital signal processor (DSP). The manufacturer doesn't tell its processing power. But considering that the E-MU10K1 provided 1000 MIPS (million instructions per second) and the first Audigy was four times more powerful, the processing power of the Audigy2 must be about equal to that of its predecessor. Is it much or little? For a better comparison: the Aureal AU8830 had 600 MIPS of processing power. The Cirrus Logic CS4630-CM processor that is used in Sonic Fury cards is 420 MIPS. We guess there was no need to invent a new processor for the new sound card, as the old one had a huge reserve left. Moreover, we didn't see hardware Dolby Digital and DTS audio streams processing. The Audigy2 can't process Dolby Digital streams in real time, as, for example, NVIDIA SoundStorm, but it can correctly output pre-encoded Dolby Digital 5.1/6.1 content. So, we have to admit that SoundStorm audio processor from NVIDIA outran Audigy2 in this respect, but maybe we will see some new things in the Audigy3? Maybe?

根據這篇文章片段看來..Audigy 2 仍然不是硬體解碼...
