Hi,
I would like to implement acoustic echo-canceller on the MIMXRT685-AUD-EVK. To this end, I would need a reference signal which is the signal played in the speaker. But, this reference signal should be synched with the signals captured by the microphones.
Usually, there is a HW loopback either from the output of the CODEC back through A2D, or from the I2S output to a different I2S input.
Can you recommend how do I configure such HW loopback?
Thanks, A.

Hello @estephania_mart ,
I know this post (I scanned the forum for echo cancellation), but it is not valuable to my questions.
Sorry, and hope to get a more concrete answer.
Thanks, AS3
