[AG-TECH] about echo cancellation equipment

[lujian]

Hi, everybody,
	I heard that soundcard powered by Crystal/Cirrus SoundFusion  DSP (digital signal processor) can do echo cancellation work . Is it possible that we use such a soundcard as a second choice of Gentner system?
	And is there anyone who can tell the difference between the card-based echo cancellation and Gentner echo cancellation?
