Analog Signal with Comparator

4 views (last 30 days)
I am planning to load an audio signal in MatLab as a matrix
signal = audioread ( 'Matlab.mp3' )
and then use a comparator with a threshold value to prepare another matrix that will store the data of the comparator and then want to plot then together or separately. I want to prepare the matrix for the comparator section because I want to use that data somewhere else as well. Is there a MatLab command to perform this comparator and matrix operation?

Please read magnitude and frequency from the signal as shown below
[y,Fs] = audioread(filename)
and then apply relational operations to compare. As MATLAB basic working is in matrix form so the result of these operations will be in matrix only. And you can use this result for further use.
