Sound designer Varun Nair has published a comparison of the sound of multiple convolution reverb plugins, including:

• AudioEase Altiverb
• McDSP Revolver
• TL Space
• Waves IR1
• Logic’s Space Designer
• Voxengo Deconvolver

Nair found that each plugin seemed to treat the IR responses differently, so that each could be used to achieve unique results.

Details on Nair’s experiments and audio examples at the Re-Sounding site.
