I believe that Harpex-B requires 4 inputs W,X,Y,Z (called 1st Order B-Format). It handily converts this to many different configurations including stereo, and one has the option of effectively changing the stereo orientation including Blumlein, X/Y, A/B etc. The requirement is the 4 inputs-- something that conventional M-S recording will not have. There are ways to convert a stereo input into B-format, however. Dan Courville's excellent Ambisonic Studio offers some really interesting ways of converting a stereo signal into the 4 B-format. Once converted, the B-Format signal can be used in Harpex-B. There are other options. Ultimately, I believe that if your input is conventional mid/side stereo, you will be able to very effectively expand and collapse your stereo field with a simple M-S decoder like Tom Erbe's free Matrix~ that is part of his Freeware package at http://www.soundhack.com/freeware/. I, too, have been struggling with these issues. Scott www.thethirdbarn.org -------------- next part -------------- An HTML attachment was scrubbed...
