> Tks for the prompt reply. However the above code does not allow me to analyse in term of a music cd. That mean, I would like the script to prompt the user to input in the file to analyse. Currently, my original code is only able to analyse .wav files. However, it wont work for .wma file.

as far as i know, reading WMA files into ML currently can only be achieved by the signal proc blockset (an extension of SL) module FROM-MULTIMEDIA-FILE...
thus, you could ...try(!)... to create a SL model to do what you want; although i doubt that the current hardware is physically able to generate a waterfall plot of a moving spectrogram in real-time...
however, others will know more (and better)...
