Developing sounds for A32NX and I have multiple times ran into an issue of not being able to orient the sound emitter vertically as this would make sounds like fuel pumps, AEVC fans etc. much better positioned in sound space and easier to get sounding right.
Right now only the azimuth (horizontal orientation) can be defined for sound emitters with "CONE_HEADING" parameter in sound.xml. It would be great if the emitter could also be oriented vertically with implementation of a parameter like "CONE_HEADING_VERTICAL".
Implementation of this needs to be done on sim level and it has nothing to do with wwise because it is defined in sound.xml. It's the same as what we already have available horizontally but just needs to be flipped to vertical axis. It would help all developers get better sounds while also saving some time now lost to getting workarounds sounding reasonably realistic.
