     The FRD Consortium is group of designers, experts, hobbyists and programmers that develop specialized acoustic design tools and simple methodology that streamline inter program operation based on Frequency Response Data file exchange. 

     The group currently includes Kristian Ougaard, Dave Scherf, Paul Verdone, John Kreskovsky, Bob Menken, Tony Gomez, Isaac MCN, Ron Ennenga, David Ralph, Yavuz Aksan, Jeff Bagby, Peter Rettweiler, Edward West, Andrew Ingram, Dan Cyr,  Martin J. King,  Charles Laub,  Daniel Wallner  &  Roman Bednarek.

     We would like to thank the Madisound site for their wonderful audio discussion board, where most of these programs were first discussed, and eventually beta tested.

 

What the heck is an FRD?

 

Using FRD tools together?
