Hi,
I create two deviceReader obeject and try to record signal from two mics simultaneously, but I find the amplitude scales of them are different, seeing in below figure.
But when I record signal with mic separately, it seems normal.
Thanks for you help!

Hello,
The difference in amplitude might be because of distance between the source of sound and the microphones. Also, it might be because of different sampling rates.
For more information , please refer to the documentation link of audioDeviceReader

Hi,
The reason is that the volume setting of two arrays are different, which can be adjusted in windows system setting. Thanks for your answer anyway!
