Hi, I have the mp3read installed already. It's the one that comes with the mirtoolbox. Some of the files without space also gave the error that it cannot be opened. I was thinking if I put the song database in a path where matlab can read. Do I have to declare a specific path to the song database in the mp3read.m file? Also, is it possible to read in songs with chinese characters as the filename?

My guess is rather that it can't open the file because you have a space in the file name? Best, Annika 2009/10/28 Markus Eichhoff <eichhoff@xxxxxxxxxxxxxxxxxxxxxxxx> Hello Go, perhaps the mp3read function would be useful. You can search in the net and download it. It is similar to wavread (a = mp3read('...mp3') ). And then you can perhaps go on with processing the 'a' with the mirtoolbox. I don't know exactly whether it works or not, but you could try.

I have a database of 3000 mp3 songs and I need to extract the mfcc features from these songs. However, some mp3 files could work with miraudio but some could not. The error is shown below. Could you help me with resolving this issue? ???
