Error using buffer Input must be a vector.

...........................

[y,~]=audioread('ty.wav'); % there is no problem in plotting y. Howerver I must find a way to normalize the signal.

a=buffer(y,800,400)

% but it sais that y is not a vector so it doesn't work with the buffer. Can anyone help?

hello

what is the size of y ? you mention there is no problem in plotting ty , but we would like to see the plot of y and not ty.

all the best

[oscillator]

size(y)=97990 2.

I'm sorry, I made mistakes when I posted the question.

1st. I want to normalize the signal.

second : I ment I plotted y

If ‘y’ is a stereo signal, it is an (Nx2) matrix. Use buffer with each column individually. (This creates code problems because similar columns from both original vectors of the buffer output need to be kept together for processing. This is not difficult, however if only the most basic buffer result is desired, it might be easier to write a loop to process segments of both columns of ‘y’ together in each iteration, rather than having to refer to matching columns of the buffer output.)

With respect to ‘normalising’ the signal, see if the normalize or rescale functions will do what you want.
