Hi Oliver,
I use miraudio(filename,'Extract',0,30,'s','Sampling',22050,'Normal');
When I looked into the source code of mp3read, I found that it uses mpg123 to
convert mp3 into wav, and then wavread the entire converted wav into
Matlab. Finally it extracts the desired part.
It explains all...
Thanks for your reply!
Sincerely,
Alan
