DestroyFX @ Smart Electronix created a Universal Binary AU version of Dreampoint / Jezar's open source Freeverb reverb algorithm.
NOTE: This is not a Destroy FX plug-in. Freeverb is an open source reverb by Jezar at Dreampoint. DFX ported it to Audio Unit, more or less to see how easy it would be to port someone else's VST plug-in to AU (it took about an hour). This AU version has no custom graphics, but Jezar's VST version never did, either. Full source code is included in the download.
