I am a beginner to use Matrix Creater. I want to konw when i use this command :
arecord --device=mic_channel8 -r 16000 -c 1 -f S16_LE test.wav
I will get a test.wav, is this wav is result from beamforming ？ when use mic_channel0-7 to record a wav is result from single channel?
Any help or suggestion is very welcome!
