Clear Comms is a PEAK mod that adds advanced noise suppression to your microphone input and the ability to preview what you sound like to other players.

It uses a library called RNNoise to filter out sounds like fans, mechanical keyboard clicks, and snack chewing.

This is a client-side mod, so it only affects your microphone's output--not other players' voices. Other players don't need to install the mod to hear the effect.

Configuration

This mod adds three new settings to the "Audio" tab in the in-game settings menu:

• Enable Noise Filtering: Turns the RNNoise filtering effect on and off completely.
• Noise Filtering Strength: Changes the strength of the filtering effect. At values close to 0.5 this may result in more artifacting or voice doubling,
• Preview Microphone Output: Loops/echoes your microphone's final outgoing sound back to your headphones so you can preview what you'll sound like to other players*

*Please note that the "Preview Microphone Output" setting won't work unless you're in a multiplayer lobby--otherwise the game isn't recording your voice!

Compatibility

As mentioned above, this is a client-side mod.

Clear Comms may not be compatible with other mods that apply filtering to the microphone input, such as Peak Suppression by hiccup or SoundGate by Curiosity_Core_Development. Specifically, enabling native WebRTC's implementations of automatic gain control (AGC), automatic echo cancellation (AEC), and/or noise suppression on top of RNNoise's pre-processing results in poor quality speech at best, and garbled audio at worst.
