Doppler

by imAETHER

Doppler, a Fabric, Forge and NeoForge adventure mod, adds the Doppler effect to Minecraft's sound engine, so moving sources change pitch as they approach or recede.

What it does

Doppler reproduces the real-world sound phenomenon in which the frequency of a sound shifts when the listener or the source is moving, which makes moving audio easier to follow by ear. Only the client needs the mod, so servers run without it and players can install it alone. Doppler requires Fabric API and is open source under the MIT License, with files for 1.18.2 – 26.2.

Key features

  1. Doppler pitch shift

    Sounds from moving sources rise in pitch as they approach the listener and fall as they move away.

  2. Listener and source motion

    The frequency change responds to movement of either the listener or the sound source.

  3. Compatible voice chat

    Doppler works alongside Simple Voice Chat and Plasmo Voice, as noted by the author.
