Seriously, I wouldn't go the MatLab route. I'd take one of the ham radio 
SW receiver projects and build a nice I/Q receiver with that. These are 
usually written in C and work almost realtime. The sound does come out 
of the speaker although there will be a delay of a fraction of a second 
versus a "real" receiver.

I did some searching and IIRC this is the one where you can configure an 
I/Q receiver:

Here is the page where it is described:

Just be patient, this web site has lots of information but is slow in 
loading.
