Arjen and Aram of Audio Ease tell us that they went by Frank Zappa's studio, The Utility Muffin Research Kitchen, to meet with Dweezil Zappa and together record the acoustics of both the tracking room and the famous Zappa echo chamber. Microphones and speaker in the echo chamber were set up just the way Frank had left them.

The samples have just been released for Altiverb, Audio Ease's convolution reverb plug-in, as part of the monthly-free-IR campaign.
