Information about the new version can be found in the paper presented at LAC2007:

by Marije A.J. Baalman, Torben Hohn, Simon Schampijer and Thilo Koch.
Further information can be found in Marije Baalman's Ph.D. thesis:

Also available as a book from VDM Verlag through various online shops.

Sourceforge also hosts swonder3Dq, software for the auralisation of 3D objects with Wave Field Synthesis, also documented in the Ph.D. thesis.
