There are two work arounds for your scenario:
- Since the total memory available to an application comprises of the RAM,and a page file or a swap file, you can increase the swap space on your system, refer to the section "Increase System Swap Space" in the link below.
2. To store large variables matlab provides an implementation of tall arrays, a typical usage to store a huge wav file as mat files is shown below:
DirIn = '<Path to your audio files>';
eval(['filelist=dir(''' DirIn '/*.wav'')']);
% Store the first audio file and append the rest to it.
[yF,Fs] = audioread(filelist(1).name,'native');
yF = tall(yF);
for i = 2:length(filelist)
[y,Fs] = audioread(filelist(i).name);
yF = vertcat(yF,y);
end
write('result',yF,'FileType','mat');
