Remote Voice Split is a client-side BepInEx 5 Mono mod for Lethal Company on Windows. It sends other players' voices to a companion audio process so remote voice and the rest of the game can be recorded on different tracks.
This project 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.
- Separates remote player voices from music, sound effects, and other game audio.
- Exposes the companion process as an application audio source without requiring a virtual audio device.
- Sends only remote-player voice playback to the companion process.
- Mutes remote voice by default when separate output is unavailable, preventing it from entering the game-audio track.
- Recovers the companion process and audio endpoint while the game remains open.

Only clients that want separate remote-voice recording need this mod. The lobby host and other players do not need to install it. Other Lethal Company versions are not currently supported.
Install a release package through a compatible mod manager, or copy these files from the package into the same plugin directory:
Lethal Company/BepInEx/plugins/RemoteVoiceSplit/RemoteVoiceSplit.dll
Lethal Company/BepInEx/plugins/RemoteVoiceSplit/RemoteVoiceSplit.AudioHost.exe
Lethal Company/BepInEx/plugins/RemoteVoiceSplit/RemoteVoiceSplit.AudioHost.exe.config
Do not rename or separate these files. Do not copy build-time BepInEx, Harmony, Unity, game, or .NET reference assemblies.
- Start Lethal Company and wait for the audio-host window to appear.
- In OBS, add an Application Audio Capture (BETA) source.
- Select the window named Lethal Company Remote Voice Split.
- Capture
Lethal Company.exeseparately for game audio. - In Advanced Audio Properties, assign the two sources to different recording tracks.
Disable global Desktop Audio or otherwise exclude duplicate monitoring when it would record the same sounds a second time. The companion process renders to the current Windows multimedia default output, so players still hear remote voice normally. Its OBS-selectable window remains available across temporary audio-device or connection recovery while Lethal Company keeps running.
BepInEx creates
BepInEx/config/com.aoirint.remotevoicesplit.cfg after the first launch.
| Setting | Default | Behavior |
|---|---|---|
General.Enabled |
true |
Separates remote voice. Set it to false to keep remote voice on the normal game output. |
General.FallbackToGameOutput |
false |
Keeps remote voice silent when separate output is unavailable. Set it to true to use the normal game output during those failures. |
Either setting can place remote voice in the game-audio track. Changes made through a BepInEx configuration UI apply to the next voice block. Disabling the mod keeps its process-lifetime routing infrastructure available, so it can be enabled again without restarting the game. The mod does not watch direct edits to the generated configuration file.
- The audio-host window does not appear: keep all three installed files
together and inspect
BepInEx/LogOutput.logforcom.aoirint.remotevoicesplit. Remote voice is silent with the default fallback setting until the host is available. - OBS shows the window but receives no voice: join a lobby with another
player, confirm that the source targets
RemoteVoiceSplit.AudioHost.exe, and check that the source is not muted. - Remote voice remains in the game source: confirm that
General.EnabledistrueandGeneral.FallbackToGameOutputisfalse. - Remote voice is duplicated: avoid capturing global Desktop Audio alongside both application sources, and remove other voice-routing mods while testing.
Include the package version, Lethal Company build, configuration, and relevant log entries when reporting a problem.
The repository pins .NET SDK 10.0.201 and all NuGet versions. The build does not require a local Lethal Company installation.
