Audiorender attenuation


I’m using the AudioRender CHOP to spatialize audio from a series of rotating movies applied onto various moving Geo COMPs. The problem I have is that given the scale of distances separating the various geometries and the listener the audio attenuation is not sufficient. When objects are far from the listener their levels don’t drop significantly as compared to when they are near.

While I guess I could scale up my entire project to increase the distances it would be much simpler to change the attenuation curve to fit my needs. There seems to be no parameter to do so in TD. Am I correct?

Also, should the size of the Geo matter or is it only it’s centroid position relative to the listener?

I’ve used Steam Audio to similar effect under Unity before and I could indeed change the attenuation curve so I assume this just hasn’t been exposed in TD yet.


Same problem for me.
it would be nice if it was exposed.

FYI, I ended up implenting the equivalent of an audio noise gate which effectively mutes all sources under a certain threshold level.

Although not applicable to all contexts this at least maintains an acceptable noise floor when the user wants to listen to a given nearby source.
