Part Number: TIDEP-0099

Hello,

This question is for the TIDEP-0099, the C6747, and the AEC/AER Library.

Can the microphones be individually echo cancelled? Is there a limit to how many?

Can multiple groups of microphones be echo cancelled? Such as, 4 pairs of microphones or 2 sets of 3 microphones.

Thanks

Nicholas,

Yes, the microphones can be individually echo cancelled and there isn't a limit as long as you have enough horsepower on the processor.

To answer your second question, the AEC would need a near-end and a far-end reference microphone input, so you individual mics would need to be somehow aggregated prior to being presented to the AEC.

Hope this helps.
