PurePath AEC module output

Jona Wernerus

Hello,

I am using the TLV320AIC3254EVM-K board and PurePath Studio (Portable Audio) GDE v5.40 Build 1 Rev. 12458.

I am trying to use the included NLMS algorithm in the AEC_32 module (see figure) for Active Noise Cancellation in Headphones.

Is there a possibility to get the estimated error/echo signal out of the module instead of the subtraction of the error/echo and the near end input signal?

Regards

Hi, i think that you can get the estimated echo signal for difference between local voice signal and measured error signal.
