Hi
Is it correct that 8 channels include the 7 raw data and 1 average data? Yes
Which channel of the sound is the average data? Channel 7 as below.
For the 7 raw data, could you let me know their corresponding microphone in the board? please refer to above pic.
Could you let me know about the exact location of the microphone in the board? (Similar to Dimension that you provided for V2 : wiki.seeedstudio.com/ReSpeaker_Mic_Array_v2.0/) please refer to above pic.
thanks
Bill
