This is a great subtle reverb with a 2.49 second decay time. Recorded via swept sine in 96/24. This set includes 9 different mic positions along with all of the formatted files for 5.1 surround for a total of 15 files. This set is great for post film and general effects. Sounds great on vocals when looking for a more implied or suggestive ambiance to current vocal and music production. This room is great on projects that require a light ambiance without the ambiance over powering the sound source. Great utility set and can be used on multiple productions and sources.
