SpatialAudioSystem
by BelugaLab
SpatialAudioSystem plays audio files inside a Minecraft world, with each sound limited to a defined area.
What it does
Players load their own MP3, OGG and WAV files, up to 10 MB per file, and play them in-game. Playback is driven by a Playback Device that can be triggered by redstone signals, so a sound can start on a rising edge, for example for a station announcement, a cutscene or ambient background audio. A Range Board marks the box where a sound can be heard, and sets how it fades out in every direction.
Scheduling covers up to 6 media items in a queue, with a play order and repeat counts from 1 to 10. Cover art embedded in an audio file is shown on device screens. Tracks sit on the server and are streamed to each client, so players hear the same playback without drifting apart. A built-in wiki screen documents the mod in-game, with hover hints and English and Japanese text.
SpatialAudioSystem is published for NeoForge on 1.21.1 only and runs on client and server, so the server and every player need it. It is released under the MIT License and is open source, with public source code, an issue tracker and a wiki.
