Name (targetname) <string>[ Edit ]

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

See also:  Generic Keyvalues, Inputs and Outputs available to all entities

Parentname:

Parent (parentname) <targetname>

Specifies a movement parent. An entity will maintain its initial offset from its parent. An attachment point can be added to the end of the name, separated by a comma.

Start Disabled (StartDisabled) <boolean>

Stay dormant until activated (with theEnableinput).

• 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 an info_target entity through which to play any sounds heard by this microphone. If specified, the microphone will consider itself in Speaker mode.

Warning: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.

• speaker_dsp_preset

<choices> Only useful in Speaker mode. If specified, when the microphone is enabled, it'll set the global dsp_speaker preset to this value. Sounds played back through speakers will then be affected by the selected DSP.

Literal Value	Description
0	Use Default

52	3 (DUPLICATE OF 1)
53	4 (DUPLICATE OF 1)
54	5 (DUPLICATE OF 1)
55	6 SPEAKER, LOUDER
56	7 SPEAKER VERY SMALL
57	8 LOUDSPEAKER, ECHO
58	9 SPEAKER SMALL
59	10 SPEAKER TINY

• Sensitivity

<float> (0-10) If the speaker is being used to monitor sound levels, this keyvalue dictates its sensitivity.

Literal Value	Description
0	Deaf
1	Normal
2-10	Increasing Sensitivity

• MaxRange

<float> (0-1024) Sounds beyond this range won't be heard, irrelevant of attenuation.

Warning:setting this to zero (or a value > 1024) when the microphone is in Speaker mode can be very bad for performance!!

Inputs

Parentname:

SetParent <stringRedirectInput/string>

Move with this entity. See Entity Hierarchy (parenting).

SetParentAttachment <stringRedirectInput/string>

Change this entity to attach to a specific attachment point on its parent. The entity will teleport so that the position of its root bone matches that of the attachment. Entities must be parented before being sent this input.

SetParentAttachmentMaintainOffset <stringRedirectInput/string>

As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.

ClearParent

Removes this entity from the the movement hierarchy, leaving it free to move independently.

• EnableDisable:

Enable / Disable

Enable/disable this entity from performing its task. It might also disappear from view.

• SetSpeakerName <target_destination>

Set the microphone to output through a different speaker entity.

Outputs

• SoundLevel <float>

Fired in Measuring mode whenever the sound level changes.

• OnRoutedSound

Fired whenever a sound is routed out through the specified speaker (if any).

• OnHeardSound

Fired whenever this microphone hears any sound it cares about.
