Niyomi - can't you just use read the next available data file from the AudioDataStore? Something like

while hasdata(myAudioDataStore)
    data = read(myAudioDataStore);
    % save the data to the mat file, do the FFT, etc.
end

where myAudioDataStore is your data store object?

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

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

Try something like this:

N = 20;
D = 'path to the folder where the files are saved';
for k = 1:N
    F = fullfile(D,sprintf('C%d.mat',k));
    S = load(F);
    Y = abs(fft(S.data));
    F = fullfile(D,sprintf('Y%d.mat',k));
    save(F,'Y')
end
