Audioease Altiverb 7 is the industry standard convolution reverb plug-in. Altiverb 7 uses top quality samples of real spaces to create reverb, ranging from Sydney Opera House to the cockpit of a Jumbo Jet. Altiverb 7 is efficient on the CPU, offers many parameters to tweak reverb, is total recall automated, and has 64 bit support. Altiverb's concert halls and recording studio spaces are geared towards music production, but also its plate reverbs and digital reverb gear. But there is more for music: algorithmic brightness, modulation, stage positioning, and tempo locked gated and reverse reverbs. And you can make fantastic textures by using any sound as an impulse response.
