Voice Chat Hydroacoustics

Inspired by Lethal Company, this mod applies an underwater filter for players that are effectively, underwater. No more crystal clear conversations while drowning!

Features

• Voices become muffled the moment a player’s head goes under the surface.
• Real-time amplitude modulation + a bubbling sound effect whenever a player speaks while submerged (the same one from Lethal Company).
• Voice range distance is cut in half when you’re underwater
• Every parameter is configurable!

Voice Chat Hydroacoustics is fully synchronized for all players in the server. You can tune each parameter of the underwater filter in real-time, and every player’s client will update instantly.

Commands

• /hydro mufflingStrength <0.001 – 1.0>: Adjusts the strength of the muffling. Lower values make voices sound deeper and more submerged. (by default: 0.02)
• /hydro voiceVolume <0.0 – 10.0>: Compensates for the muffling by boosting the speaker’s gain. (by default: 3.0)
• /hydro garglingEffect <0.0 – 1.0>: Controls the intensity of the choppy bubbling modulation applied to the voice. (by default: 0.5)
• /hydro bubblingSound <0.0 – 2.0>: Sets the volume of the bubbling sound effect that plays when people talk underwater. (by default: 0.05)
• /hydroacoustics voiceDistance <1 – 100>: Sets the maximum block range players can be heard and hear when they’re submerged. (Default: 16.0)
• /hydroacoustics defaultValues: Instantly restores all settings to their original defaults.

Possible Future Changes

• Extended version support
• Make the filter apply to any entity that reproduces a sound underwater (currently only affects players).
• Perhaps an underlava filter?
