Thanks so much Augustine! I’m actually taking a lot of existing 3d signals and trying to squish them into this irregular 12 channel setup. HOA and 7.1 mostly as well as signals from Sound Particles so SPAT Revolution has been helpful (though ICST looks amazing), even though Im not automating movement at that point. Trying to keep as much of the workflow channel based as possible.
1. There seems to be an issue with directionality of speakers in SPAT when I select DBAP. Some point left and others point right when really I want them all to point towards the floor. Is this just a user interface problem? Does DBAP treat speakers as omnidirectional? 2. Good to know about not using delays for non-sweet spot dependant projects. Would same go with normalization? 3. Fantastic about REW. Do you know of any tools that can figure out the coordinates of irregular speakers just from a sweep or test signal so I dont have to measure irregular speaker installations by hand? Also looking at GRM Spaces rew Thanks so much, Jon On Aug 18, 2019, 5:26 AM -0600, Augustine Leudar <augustineleu...@gmail.com>, wrote: > also you could use rew to eq each individual speaker.
