Thread: Microphone AEC/Noise Cancellation

I've read a few posts about microphone acoustic echo cancellation and noise cancellation but haven't really seen anyone come to a firm conclusion. Noise cancellation isn't an issue but echo cancellation seems to be.

My question: Is there *any* solution for CarPC users to have phone echo cancellation? I intend on mounting a microphone in my car and integrating my phone through Centrafuse but having an echo would be an issue.

I have read about the Phoenix SOHO, but I have no PCI slots - so any PCI based hardware solution is out of the question (and would be for many people with CarPCs).

I hope someone can shed some light on this!
