Fremitus room acoustics
Fremitus’s Room Acoustics presets are built on impulse responses measured in real spaces. Two of them come from OpenAIR, the Open Acoustic Impulse Response Library, under the Creative Commons Attribution-ShareAlike 3.0 licence. As that licence asks, the versions modified for Fremitus are available here under the same licence.
