I posted a patch against toolame-02l about a year that adds what I suspect is 
precisely the capability you're talking about here --i.e. generate an 
MP2-encoded .WAV file with the proper BWF-compliant header chunks that 
Prophet requires.  You can get it at:

This was in order to support use with the Rivendell Project:

BTW, the MP2-encoded WAV file isn't a proprietary format, but follows an EBU 
(European Broadcasting Union) standard known as 'Broadcast Wave File', or 
'BWF' for short.  You can find the full spec at:
