I need to apply blackmanharris window on an audio file (for framing with 50% overlap) and dft each frame?

%audio file reading.

[input,Fs] = audioread('1.mp3');

% determine the number of rows/frames.

w_length=128;

m         = length(input);

numFrames = floor((m-1)/w_length)+1;

% allocate memory to the frame matrix.

frameData = zeros(numFrames,w_length);

%Creating a blackmanHarris Window.

window_1=blackmanharris(numFrames,'periodic');

Kindly provide the assistance from here on-wards
