MATLAB: Select ‘DeviceName’ for dsp.AudioRecorder and dsp.AudioPlayer

Question

I was wondering if the DSP blocks have a way of listing the available audio devices in my computer similar to what the audiodevinfo function does? The problem I'm having is that when I use audiodevinfo it only returns a partial name of the available devices and not the full name of the device so I can't assign this name to the DeviceName parameter in dsp.AudioRecorder or dsp.AudioPlayer from the Command Window in MATLAB…

so, this is what I'm doing:

h = dsp.AudioPlayer;

h.DeviceName = audiodevinfo(0,1);

and, this is the error I get:

??? Error using ==> CompEnum.findMatch at 60 Communications Headphones (IDT is not a valid setting for the DeviceName property.

Error in ==> C:\Program Files\MATLAB\R2010b\toolbox\shared\system\+matlab\+system\@APIProp\APIProp.p>APIProp.checkForEnumProp at 433

I appreciate any help I can get!

Answer 1

Enter

devinfo = audiodevinfo;

then look at

devinfo.output

the name there should be a valid DeviceName property.

The easiest way is to use tab completion on the System object property

h = dsp.AudioPlayer;

then type the following

h.DeviceName = '

after you type the first single quote, hit the TAB key, you should see a list of valid device names.
