AudioDeviceInput
Inherits from: Instance → Object
AudioDeviceInput produces audio streams from physical devices, such as microphones. It provides a single Output pin which can be connected to other pins via Wires. AudioDeviceInput has properties for selecting which Player is producing the stream, and controlling whether or not they are muted.

AudioDeviceInput.AccessType
Determines whether the list of user IDs provided to SetUserIdAccessList is treated as an allow-list or deny-list.
If AccessType is AccessModifierType.Allow, then only the supplied user IDs are permitted to hear this AudioDeviceInput. If AccessType is AccessModifierType.Deny, then only the supplied user IDs are blocked from hearing this AudioDeviceInput.
Since player voices are networked, this property should only be assigned from the server in order to replicate properly.
