Hello,



I would like to know if it is possible when configuring the Mic Array V2 in 6 channel firmware to get each Mic audio after applying AEC? So instead of getting the final processed audio in one channel, get each mic channel with AEC applied (instead of raw).

Hi there~, We only have the 6 channel firmware with 4 raw channels. What is your application for the 4 raw channels with aec functions? It will plenty of xmos resources and not appreciable. Thanks

Hi,We are developing a system where we need ambisonic sound (4 mic input) for 360degree. We also have a speaker output. But of course each mic input needs to have AEC applied. Is this something your team could adapt the firmware? Could this be done on the ReSpeaker Core 2?Thank you

Hi, I double confirmed with software team that both mic array v2.0 and core v2.0 can not support this function. you can consider to use the mic array v2.0 to capture the raw channel and playback channels. As you have a controller, you can do some open source AEC algorithm to get the raw data with aec applied.Thanks
