Audioread in loop faster way

Hello, i need to read multiply audio files so i wrote
for idx=1:Num
filename =['my_dir\data\a',int2str(idx),'.wav'];
x{:,idx}=audioread(filename);
end
,but it's very time consuming (let's say about 200 wav files) , so maybe there is any other faster way to do this? thanks in advance.

One thing you can try is use Parallel Computing Toolbox and read data from each file on a different MATLAB worker. That is the only way I can think of to speed up the operation.

Hello, well i tested the time for reading 5 audios and with for loop the time is almost the half as with the parfor. With the parallel computing maybe there is any other function that you were refenring? , but with parfor it's not what i was expecting. Anyway thank's a lot it's always pleasure to learn new stuff in matlab. Note the time was calculated with tic/toc.
