Please understand that INSP:IR was developed by our Hungarian colleagues from Inspired Acoustics, so we don't know as many details as we do when it comes to our own products. But in principle you are right: The INSP:IR library offers a few features that you can find in MIR on a larger scale, like impulses emitted into different directions, form different spots on a stage.
