Keyvalues

• Template:Kv targetname

• target

<target_destination> If the speaker is in Measuring mode, this is the name of the entity where the sound level is to be measured.

• SpeakerName

<target_destination> The name of a speaker entity through which to play any sounds heard by this microphone. If specified, the microphone will consider itself in Speaker mode. Cannot be an env_speaker!

• ListenFilter

<filterclass> The name of an filter entity which specifies the only entities the microphone can hear. Sounds emitted by other entities will not be heard.
