The Audio Tap components are available in the Vivox Unity package. With the package installed, you can add the taps through both the GameObject and Component Addition menus under Audio.

Adding a tap adds an Audio Source component to the associated GameObject. You can modify the audio provided by the taps directly through GameObject components, such as the components supplied by Unity under Audio, or by routing it through an Audio Mixer.

As shown above, in the Vivox Channel Audio Tap component screenshot, every Audio Tap has a visible loudness meter in its Inspector window to help monitor the audio stream activity during Play Mode.

Audio Mixers can also modify tap audio. After creating the Audio Mixer, in the Audio Source’s Output field, select the required Mixer Group to route the audio through the mixer. Note that all the components added to the Audio Source GameObject are applied before sending the audio to the Audio Mixer Group.

Audio Taps will only work when connected to a channel.

Taps will work in both positional (3D) and non-positional (2D) channels. In positional channels the participants must be within the audio range to hear each other.

As of the 16.2.0 version of the Vivox package you can have more than one Participant Audio Tap applied to the same user across channels. However, if the Silence In Channel Audio Mix parameter is set to True at some point in the chain of taps, all following taps will be muted.
