Picture below is the result from the firmware installation.
Then, I tried using this Mic Array to record sound via Audacity. This is the result which are from my built-in microphone and Mic Array.
As you can see from the wavelength, recorded sound of Mic Array (the below one) is full of noise compare to my built-in microphone. Is there anything I can do to resolve this problem ?
I've tried installing back the to ReSpeaker_Mic_Array_firmware_xvsm_0x32_20170329.bin which is the initial firmware. Actually, the Mic Array should blink the LED light from the direction of the sound coming through, however; it's continuously blinking on one sided as you can see in the picture below.
After installing new firmware for Windows from https://github.com/respeaker/ReSpeaker_Microphone_Array_Firmware (which is output 8 channels mic raw data - ReSpeaker_Mic_Array_firmware_raw_0x82_20170329.bin) using this driver https://github.com/Fuhua-Chen/ReSpeaker_Microphone_Array_Driver (ReSpeakerMicrophoneArrayDfu.exe is the one used for firmware installation).
