Hallo, I need to read and work into a matlab code block with the data coming from the ALSA Audio Capture block inside Simulink frame. I'm using Matlab r2013a and matlab r2013b, with raspberry Pi Simulink libraries.
That's because i need to develope a special audio analysis.
So my question is: How can I read the stream of data coming from the "Raspberry Pi Audio Capture" block, and modify them before to "plot" or "record" the modified data into a file?
And how to plot such a kind of data in a streaming plot?
And how to record such a kind of data into a file?
