Audio Ease ALTIVERB-XL

Altiverb 5 is a convolution reverb plug-in for Mac OS X and Windows XP. It uses top quality samples of real spaces to create reverb, ranging from Sydney Opera House to the cabin of a fire truck. Altiverb 5 offers the most extensive set of parameters, it supports all professional plug-in formats, parameter automation and surround (currently Mac only). Altiverb 5 gives you a choice between iLok SmartKey or Challenge/response copy protection, it lets you sample your own spaces (currently Mac only), and Altiverb taxes your cpu the least of all convolution reverbs.

But most importantly: in the end a convolution reverb sounds as good as its samples. Audio Ease's 3 year longer experience than anyone else in the industry ensures Altiverb's samples are unsurpassed in quality, quantity and diversity. And you get free new ones every few weeks.
