Creating a music player with matlab

Hi, I am creating a music player in matlab. One way to play sound is to read the wav file as
[record,fs] = wavread('filename');
sound(record,fs);
But that approch is not very effective because it allocates a lot of memory to variable record
I have another idea in my mind. I'll read a small number of samples
[record,fs] = wavread('filename',[n1,n2]);
sound(record,fs);
and then I read next set of samples and play them and this process will go on till the end of file. But I am not able to come up with some algorithm to accomplish it.
I have however figured out how to compute number of samples in a file.
siz = wavread('filename','size');
I tried this step
i = 1;
n1 = 1;
n2 = 100;
siz = wavread('filename','size');
siz1 = siz(1,1);
while(i < siz1)
[record,fs] = wavread('filename',[n1,n2]);
sound(record,fs);
n1 = n1+100;
n2 = n2+100;
i = i+100;
end
but it's not working. Please help me figure out the correct procedure to implement by idea.

You may want to look at audiorecorder and audioplayer
alternatively, if you have DSP System Toolbox, you can also use dsp.AudioRecorder, dsp.AudioFileReader, and dsp.AudioPlayer

audioplayer does not offer any obvious way to queue additional samples as you go. The DSP functions do appear to offer that possibility.
