This isn't just a reverb plug-in. This is a hugely tricked-out ultimate convolution reverb with all the stops pulled.

Altiverb first popularized the use of sampled spaces for software reverbs via a digital technique called convolution. As I reported here, Altiverb 5
brings plenty of new features, including new controls for where your
audio is 'heard onstage,' four band reverb EQ for controlling separate
frequencies of your sound, and CPU controls so you don't max out your
processor.

  • Mac OS X Only with support for every format: HTDM / RTS / AudioSuite (Digidesign), MAS (MOTU), and, of course, VST and Audio Units
  • Reverse reverb mode because there's nothing quite as sweet as hearing reflections first
  • Explore reverb visually with three-dimensional waveform views, pictures of sampled spaces, and even VR movies

And lots more. Copy protection evidently lets you choose between iLok and challenge/response.

Now here comes the sticker shock:
US$595 buys you first-class convolution luxury. (US$895 for Pro Tools
users.) If you're an AltiVerb vet, though, you can upgrade for $169-269.

Just want the sampled impulse responses? US$39.95 buys you the impulses
for loading into reverbs like Logic Pro's Space Designer. But no VR
movies, of course.
