Whether the downloaded AudioClip is marked as ambisonic.
When true, Unity treats the downloaded AudioClip as ambisonic audio. The project's ambisonic decoder plug-in then decodes the audio based on the orientation of the AudioSource and AudioListener.
You can set this property before accessing audioClip, or pass true for the ambisonic parameter in the constructor or UnityWebRequestMultimedia.GetAudioClip.
Note: Changing this after the AudioClip has been created has no effect.
