Audio volume

Changing microphone gain (local input volume)​

The console variable voice.MicGain controls the gain of the local microphone capture. Do not use the original engine console variable voice.MicInputGain as this will have no effect on the plugin.

Microphone auto leveling volume​

Enabled by default the plugin will automatically level the microphone volume so your voice stays smooth for other players. The console variable voice.MicAutoLevel (enabled by default) controls this setting.

Changing remote player voice volume​

There are multiple ways to change the volume of other (remote) players.

The cleanest way is to use sound classes.

Go to Edit -> Project Settings -> Onset VoIP Settings -> Voice -> Playback and set:

  • Default Sound Class 3D for proximity, world voice channel 0, and speaker components.
  • Default Sound Class 2D for 2D voice channels.

Onset VoIP applies these settings to the voice UAudioComponent as its sound class override. You can then change the remote voice volume on the sound class like you would for other Unreal audio.

Using Audio Volumes, reverb, and submix sends​

Because remote voice playback uses a normal Unreal UAudioComponent, sound class settings also let voice participate in Unreal audio routing.

For example, to make proximity voice react to Audio Volumes that route to different reverb submixes:

  1. Create or choose a sound class for 3D voice, for example SC_Voip3D.
  2. Configure that sound class the same way as your other spatial sounds, such as enabling Send to Master Reverb Submix if your project uses Audio Volume reverb sends.
  3. Set Default Sound Class 3D or Default Sound Class 2D to that sound class in the Onset VoIP settings.

When the listener moves through Audio Volumes, Unreal can then route the 3D voice through the active reverb/submix settings, such as a hallway submix in a hallway Audio Volume and a smaller room submix in a room Audio Volume.

Built-in volume console commands​

Another way is to use these built-in console commands.

voice.volume3d sets volume on all 3D audio (proximity, voice channel 0 and speaker components). voice.volume2d sets volume for voice that you hear through voice channels.
