Sound Physics: Aeronautics

by alecjohnson45

Sound Physics: Aeronautics changes how sound behaves around moving ships, so audio from Create Aeronautics vehicles is muffled, delayed and occluded by hulls and terrain.

NeoForgeClient required, server optionalGNU General Public License v3.0 onlyOpen source1.21 – 1.21.1

What it does

The mod extends Sound Physics Remastered to Sable sub-levels and Create contraptions. Sound is muffled when it passes through a ship hull, and the difference between exterior and interior listening positions is modeled. Moving sub-level blocks and mounted machinery count as acoustic obstructions, so audio stays positionally accurate while a craft turns and travels.

Large high-RPM Aeronautics propellers carry far beyond the 48-block vanilla range. Their reach grows with propeller size and speed, and distant sound becomes softer and more subtle as it fades. Doppler effect and configurable positional sources are included. Optional Distant Horizons support lets far propellers be checked against LOD terrain, so mountains and ridges muffle them.

The mod requires NeoForge and Sable, along with the Create and Create Aeronautics addons that supply the vehicles. It is a client mod: players must install it, while the server may run without it. Files are published for 1.21 and 1.21.1, and the latest build is 2.0.1 for 1.21.1. The project is open source and licensed as GPL-3.0-only.

Key features

  1. Sub-level muffling

    Sound is muffled as it passes through ship hulls and moving sub-level geometry.

  2. Exterior and interior sound

    Listeners inside a craft hear a different mix than listeners standing outside it.

  3. Long-range propellers

    Large propellers are audible at distances that scale with their size and rotation speed.

  4. Doppler and positional sources

    Doppler shifts and positional sources follow moving crafts, and their settings can be adjusted.

Use cases

Who it’s for: Players who fly Create Aeronautics vehicles and want their audio to match the ship's position and surroundings. Players using Sound Physics Remastered on other vehicles should check the compatibility note before installing.

Questions

Does Sound Physics: Aeronautics need Sable?

Yes. The mod is built around Sable sub-levels and Create Aeronautics, so Sable must be installed alongside it.

Can Sound Physics: Aeronautics run with Sound Physics Remastered?

No. The mod replaces Sound Physics Remastered rather than adding to it, so only one of them can be installed at a time.

Does the server need Sound Physics: Aeronautics?

No. Players need it in their own game, while a server can run without it.

What the author says

Sound Physics Aeronautics is a fork of Sound Physics Remastered built around Create Aeronautics and Sable moving sublevel acoustics. This mod integrates previously "ignored" Sable sub-levels and Create contrpations to the geometry of Sound Physics Remastered. It also adds the doppler effect, long range propeller…
