Blue Mountains - Dynamic Voice Chat System (VoIP)

Version 2.0 of the plugin is now live on fab.com for UE 5.5+. Join the new Discord server for help and support.

2.0 is a major update focused on voice quality, microphone reliability, network resilience, platform support, and even easier setup.

See the changelog for a full list of added features and improvements.

Add feature-rich voice chat to your Unreal Engine multiplayer project without relying on an external voice service or separate voice server.

🔊 Features

  • Proximity voice (3D) and voice channels (2D) for global chat, teams, radios, phones, and more.

  • Replicated speaker components for radios, PA systems, intercoms, cameras, vehicles, loudspeakers, and other world objects.

  • Clearer and more reliable voice with noise suppression, automatic microphone leveling, jitter buffering, and packet-loss recovery.

  • Zero-config setup. Enable the plugin and get started without modifying your Pawn or Character Blueprints.

  • Uses your existing Unreal networking. No external voice service, separate voice server, or Unreal session is required.

  • Supports dedicated and listen servers and only sends voice data to relevant players.

  • Supports Windows, macOS, Linux, Android, iOS, and Pixel Streaming.

  • Change the microphone at runtime and customize input gain, player volume, spatial attenuation, and voice effects.

  • Record local or remote voice to PCM, WAV, or MP3, including voice processed on dedicated servers.

  • Includes full source code with Blueprint and C++ access, talking-state events, and customizable nameplates.
