MATLAB: How to convert audio signal having (4.82MB size ,44100 as sampling frequency , stereo signal ) to different frame length that is 1024 samples,512 samples and 2048 samples?Whether I should resample it if not than how is it possible in matlab

Question

my second question is that Can I convert this signal to different sampling rate also I mean at 22050Hz,48000hz etc.?or at different time interval 14.34 seconds,57.36seconds ?And its actual length in seconds is 28.68 seconds and total number of samples is 1264896?

Answer 1

   framesize = 1024;
   framedSignal = permute(reshape(YourSignal.', 2, framesize, []), [2 1 3]);

Now the first dimension of framedSignal is the sample number, the second dimension is the channel number, and the third dimension is the frame number.

To convert the frame rate see http://www.mathworks.com/help/signal/ref/resample.html
