You could use "Goldwave" for this purpose.
WAV <-> RAW
MP3 <-> WAV
You can do transformation to any popular audio format.
visit www.goldwave.com for additional details.

Subject: [matlab] reading wave files
I am currently trying to do some simulations of a graphic equalizer that I
am designing using FIR filters and I am having problem reading in wav files
that are just standard music. I am getting an error 85 and it says it is in
the "wrong format". Is there a proper way to convert a mp3, or audio
track
to wav so that I can read it in and record the outputs to another wav file?
Thanks
Craig

To use wavread in MATLAB the audio file should be in
Microsoft WAVE sound format. If it is a normal PCM
file you can simply use fread without any problem if
you already know the number of bits per sample.
For converting mp3 to wave, in some audio players the
output can be configured to a file instead of audio
devces. In Winamp you can do this by going to
options->preferences->output and choosing disk writer
plugin. I think this produces a wave file.
You can also search google for mp3 to wave conversion.
But most programs might be commercial.

I'm interested to know more about your FIR equaliser, are you designing
a
multi-rate system?
