I've been putting together a patch to do some ambisonic remapping of 5.1 mixes to a planetarium setup with a 15.1 dome arrangement. So far I've been using the ICST tools, which are pretty awesome. Overall the tools seem to work as planned, but I'm having a hard time "sharpening" the localization.
If I map the source exactly to a speaker position and send a signal out of it I would expect it to come out of that speaker alone, but I'm getting a ton of spreading and thus vague localization. I feel like I've adjusted pretty much every parameter to no avail. I'm hoping there's a few seasoned folks who might be able to help out.
Here's the patch I've started. It's still in the works, but in presentation mode zoomed out it helps. It defaults to ITU 5.1, but if you select "Matched Speaker" and send a sine/noise signal to it I would expect to see a near matched output at the speakers. Instead you see a massive amount of signal in all the other speaker outputs.
