The help file for the Wwise SDK 2021.1.1 says the following in Sound Integration Walkthrough > Terminate the Different Modules of the Sound Engine >Terminating Spatial Audio:
If it has been initialized, Spatial Audio should be terminated before the sound engine.
void TermSoundEngine() {
// Terminate Spatial Audio
AK::SpatialAudio::Term();
}
In the actual Wwise help page in the web browser, the link to the definition of AK::SpatialAudio::Term() points to AK::Comm::Term().
Looking at the AkSpatialAudio.h file, there actually isn't a Term() method declaration anywhere.

So how should the Spatial Audio engine be terminated after calling AK::SpatialAudio::Init()? It seems like every other module does have a Term() method defined.
