Remote Voice Split

A Lethal Company mod that separates other players' voices from the rest of the game audio so each can be recorded on a different track.

This package is currently in public beta. Real-world testing remains limited, and issues such as reduced game-audio quality, latency, missing audio, or incorrect audio routing may occur.

Compatibility

• Lethal Company v81 (2026-04-17 UTC)
  • Steam Manifest ID: 6423525044216269478
  • Test environment
    • BepInExPack v5.4.2305 (2026-03-17 UTC)
• Windows with .NET Framework 4.8
• OBS Studio Application Audio Capture

What it does

• Moves voices from other players into a companion audio process.
• Keeps music, sound effects, and other game output in the normal Lethal Company process.
• Uses the current Windows multimedia default output for the companion process.
• Mutes remote voice by default when separate routing is unavailable so it does not enter the game-audio track.
• Keeps the OBS-selectable window available during temporary audio-device or connection recovery while the game runs.

Setup

1. Install the package and start Lethal Company.
2. Wait for the Lethal Company Remote Voice Split window to appear.
3. Add that window as an OBS Application Audio Capture source.
4. Capture Lethal Company separately and assign the sources to different recording tracks.

Configuration

BepInEx creates BepInEx/config/com.aoirint.remotevoicesplit.cfg after the first launch.

Either setting can place remote voice in the game-audio track. Changes made through a BepInEx configuration UI apply immediately.

Who needs to install

Client-side only. The host and other players do not need to install this mod.

Install it on each client that wants to record remote player voices separately.
