ReSpeaker 4-Mic Linear Array with PyAudio

Dear all, a question regarding using PyAudio with the 4-mic linear array. If I set the “channels” to 1 when opening the stream in PyAudio, is the output the processed signals from all 8 channels? Below is the sample code. Thanks.

CHANNELS = 1
p = pyaudio.PyAudio()
stream = p.open(format=FORMAT,
channels=CHANNELS,
rate=RATE,
input=True,
frames_per_buffer=CHUNK)
print("* recording")
