I have wrote about this on AITB forum 1 week ago but nobody replied so I'm going to repost it here:
Some of the EAR Rooms presets are slighty out of phase in my DAW, the EAR Studio2b for example. Can anybody check that and help me debug the issue? Maybe its me or maybe not, anyway I've noticed that as I've changed the Nebula Buffer, the phase moved and other presets got affected by a small cancellation. This is happening in Ableton Live via Insert and Send. Im going to check on another daw. Please let me know
As you can clearly see in the second image, scroll to the bottom right corner, you can see the slight phase cancellation. As I said this is not happening with all the presets, in the example I've used the Perc Room.
