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

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.

Note: in your release the link to your example should be https://www.mathworks.com/help/releases/R2018b/wavelet/examples/music-genre-classification-using-wavelet-scattering.html

data(45001, :) = 0;
data = data(1:45000, 1);
No if needed, and handles multiple channels converting to single channel.

It will take me more searching and testing. It turns out that audioDataStore ignores custom readFcn so it might be necessary to recode it for to use a datastore of type 'File'.
