Hello, can anyone tell me what y really means here? [y,Fs] = audioread(filename) I know that y is audio samples represented as a matrix, but what does it really mean? any idea...
The same question// How can I get the frequency and the amplitude of each audio sample in y ?

Towards the bottom:
'Audio data in the file, returned as an m-by-n matrix, where m is the number of audio samples read and n is the number of audio channels in the file.
  • If you do not specify dataType, or dataType is 'double', then y is of type double, and matrix elements are normalized values between −1.0 and 1.0.
  • If dataType is 'native', then y can be one of several MATLAB® data types, depending on the file format and the BitsPerSample value of the input file. Call audioinfo to determine theBitsPerSample value of the file.'
Hope this helps
