2 inputs from Stereo MIC to Simulink

Hello,

We're are trying to get two different inputs from the Stereo MIC in to MATLAB Simulink. Each signal needs to be processed differently at the same time.

We tried to use the Multiport selector and the submatrix blocks to separate the left and right channels from the Stereo input.

The problem is that if we give different inputs to each channel, in Matlab they're not separated using these blocks as they should be. We're displaying the output on two scopes and the output is the same for both channels (though the input is different).

Does anyone know why we're not getting the same output?

Thanks!

I suspect people might want to see a diagram of your model.

Thanks Walter.

Here is a diagram of the model: http://imageshack.us/photo/my-images/560/123gbg.png/

What about if you use the Demux block instead?

We tried this block and it gives an error saying it does not work with matrix inputs. The stereo signal is a matrix
