MATLAB: How to truncate number of sample in audiofiles using audioDatastore function in MATLAB

Question

Hi all

I am using audiodatadatastore function to classify my speech signal using wavelet scattering . Unfortunately all my audio files are having different length or sample size. I want to make it uniform for all files.

I did try following

% while hasdata(ads)

% [data,info] = read(ads);

%

% if length(data)<45000

% data=[data;zeros(45000-length(data),1)];

% else

% data=data(1:45000);

% end

% end

But that’s of no use. Help is highly appreciated.

Answer 1

data(45001, :) = 0;
data = data(1:45000, 1);

No if needed, and handles multiple channels converting to single channel.
