Directivity patterns, occlusion and reflections

[noahneumark]

I'm working on writing components for A-Frame that utilize the Resonance Audio Web SDK. I need clarity on these properties as the documentation is rather limited at this point. I don't see that the Web SDK explicitly allows access to occlusion and amount of reflections -- only material coefficients.

I've also played around with the directivity patterns, and it's difficult to debug without any visual cues. My approach has been to move around a visible sound source, change my angle of approach and listen for changes in the frequency spectrum. The problem is that the subtleties are hard to discern especially with the interference of the reflections. It does not seem that the forward position of the sound is linked with the forward position of the object even though the I am using setFromMatrix on the object's Matrix4 object. Increasing sharpness, and setting alpha to 0.5 (cardioid) does not result in what I would expect. I'm not clear on the difference between sharpness and sourceWidth.

It would be great to get more documentation on these properties, clarification on the discrepancies I am experiencing, and if there was a way to visually represent the positioning and shape (at least in the documentation) that would tremendously help my development.

Thank you!
