Each ReverbType option for this property corresponds to a preset available in the FMOD sound engine. For example, when AmbientReverb is set to ReverbType.Hangar, sound will reverberate differently to simulate being in a large enclosed space.

Changing AmbientReverb affects the following properties used by Roblox's sound engine.

• Reverberation decay time.
• Initial reflection delay time.
• Late reverberation delay time relative to initial reflection.
• Reference high frequency.
• High-frequency to mid-frequency decay time ratio.
• Value that controls the echo density in the late reverberation decay.
• Value that controls the modal density in the late reverberation decay.
• Reference low frequency.
• Relative room effect level at low frequencies.
• Relative room effect level at high frequencies.
• Early reflections level relative to room effect.
• Room effect level at mid frequencies.

The number of studs to be considered a meter by SoundService when calculating volume attenuation of Sounds parented to a BasePart or Attachment.

By default, this property is 3.33, meaning that a meter is considered 3.33 studs for the purposes of volume attenuation. The greater the DistanceFactor, the more gradually sound will attenuate.

It's recommended that you only change this property if your experience uses a different scale. For example, when using larger custom characters, you may want to reduce DistanceFactor.

This property determines the degree to which the pitch of a Sound varies due to the Doppler effect, a phenomenon whereby the pitch of a sound changes as the source and observer of the sound move further away or closer together. Only affects Sounds that are parented to a BasePart or Attachment.

Increasing this value exaggerates the impact of the Doppler effect, whereas decreasing it minimizes it. By default, the value of this property is 1.

This method returns the SoundService current listener type and what is set as the listener, meaning the point from which audio in the experience is "heard" by the player. By default, the listener is set to Workspace.CurrentCamera. The listener can be changed using SetListener().

The first result returned is the listener's ListenerType and the second result is dependent on that type:

Plays a Sound locally, meaning the sound will only be heard by the client calling this method, regardless of where it's parented to. This method is most useful for playing a Sound locally in the Studio client, for instance in a Script for a Plugin.

This property determines whether Sound playback is replicated from the client to the server, and therefore from the server. In other words, when a LocalScript calls Play() and this property is true, the sound will only play on the respective client. If this property is false, other clients will also hear the sound.

Default is true, meaning filtering is enabled.

Sets how fast Sound volume attenuates. The higher the RolloffScale, the more rapidly a sound's volume will attenuate as the distance between the listener and the sound increases.

Note that this property only applies to Sounds whose RollOffMode property is set to Inverse (default) or InverseTapered. Linear and LinearSquare modes use a different attenuation model which is not influenced by this property. This property also has no impact on Sounds which are not parented to a BasePart or Attachment.

Sets the listener used by the client, meaning the point from which audio in the experience is "heard" by the player. For Sounds parented to a BasePart or Attachment, the listener influences the volume and left/right balance of a playing sound.

By default, the listener is set to Workspace.CurrentCamera, but a range of different types of listeners can be used.

The listener can be retrieved using GetListener().
