Thank you for providing fascinating ReSpeaker things . I using mic array v1 with raw firmware to record human voice and found that the 8th channel of the recording is also human voice. That’s nonsense since we have only 7 micphones on board. I wonder if SeeedStudio could update the raw firmware to setting the 8th record channal capture the playback audio,so that I could fetch both the musics and human voice for my own AEC algorithm .
It would be even great if SeeedStudio could open the raw firmware sourcecode,many extended things can be done by then .
the 8 channels include the 7 raw data and 1 average data without aec function. the product is end of life and we will not update the firmware any more. we signed nda with xmos and the source file will not be released. we released mic array v2.0 and it has better performance include the AEC function. please refer to
