Hi We are trying to access multiple channels from an audio card using the "dsp.AudioRecorder" and the "step()"-function. In version 2014a, MATLAB allows for x number of channels specified in the AudioRecorder, while for version 2014b we only have access to either channel 1-2, 3-4 or 5-6. The DeviceName in version 2014a for the sound card was "OCTA-CAPTURE", while in 2014b, it is '1-2 (OCTA-CAPTURE)', '3-4 (OCTA-CAPTURE)' and so on.
Is it possible to change back the devicename such that it is possible to access several channels like in version 2014a? Or is there some other way of accessing multiple channels using AudioRecorder? We have tried another sound card resulting in the same kind of problem
Thanks, Frank
