I would like to record audio from 4-ch microphone array device named PSEye (PlayStation). I downloaded driver and the system (Windows7 64 bit) successfully finds the device as audio input device. However, on MATLAB, using 'audiorecorder' function, it can record up to only 2 channels. Is there any way to record 4-ch MIC signal?

Thank you for your reply :) I tried that code, but it shows error message as follows. An error occured while using the portaudio stream Error number: -9997 Error message: Invalid device ID. I'm wondering if there is any example file for the pa_wavrecord function

Use the dsp.AudioRecorder systemm object to record more than 2 channels of data.

The line:
AR = dsp.AudioRecorder(16000,'NumChannels',4,'OutputNumOverrunSamples',true);
assumes that your 4 channel device is the default device on your system? Can you confirm that using the Windows Device Manager?
Are you using ASIO or DirectSound to communicate with the device? Check the DSP System Toolbox preferences.

I'm with the same problem, using the PS3 Eye on Win7 and Matlab 2018b. Did you find a solution?
