BuroSound

BuroSound

BuroSound is a client-side mod that allows map-makers and resource-pack creators to bind custom music and ambience to specific 3D regions in Minecraft. Enter an area, and a track smoothly starts. Leave it, and it fades out or transitions to another. Everything is configured entirely via sounds.json.

Key Features

• Spatial Audio Without GUIs: Setup requires no in-game interfaces—everything is controlled via versionable JSON in your resource pack.
• Playlists & Chains: A track can automatically trigger the next one when it finishes.
• Smooth Transitions: Supports audio fading when moving between locations and dedicated “exit zones” to stop playback.
• Note Block Compatibility (Ducking): When note blocks play, BuroSound’s background music temporarily lowers in volume so contraptions and melodies remain audible.
• Debugging Tools: A visual in-game overlay displays the exact boundaries of your music zones.

Installation

For Players

1. Install Fabric Loader and Fabric API.
2. Place the BuroSound .jar file into your mods folder.
3. Enable a resource pack containing zone configurations (without it, the mod does nothing).

For Content Creators

The mod reads the assets/minecraft/sounds.json file from your resource pack. Simply add specific parameters to your sound events inside the sounds array. To apply changes in-game, use F3 + T (reload resource packs).

Parameter Reference (sounds.json)

The following fields can be added to any sound event within the sounds array. All coordinates are specified in blocks.

| Parameter | Type | Default | Description |
| :— | :— | :— | :— |
| box | [int] or [[int]] | None | 3D trigger zone for the sound. Format: [x1, y1, z1, x2, y2, z2] or an array of such zones. |
| dimension | string | minecraft:overworld | The dimension where the zone is active. |
| exit / isExit | boolean | false | If true, the zone acts as an exit trigger: it smoothly stops current music and clears the queue. |
| next | string | None | ID of the next track. If provided without a dot (.), the mod automatically adds the music_disc. prefix. |
| play_while_inside / playWhileInside | boolean | false | If true, the music fades out immediately upon leaving the zone. If false, the track plays to the end even if you leave. |
| ignore_note_blocks / ignoreNoteBlocks| boolean | false | If true, this track will not be ducked (lowered in volume) when note blocks play. |
| allow_overlap / allowOverlap | boolean | false | If true, the sound from this zone can play simultaneously with sounds from other zones. |
| block_trigger / blockTrigger | array or object| None | Alternative activation method: right-clicking a specific block at the specified coordinates. |

Argument Examples

1. Basic Zone & Dimension (box, dimension)

A standard zone in the Nether. The track starts upon entry and plays to completion, even if the player leaves the area.

{
  "music_disc.nether_ambient": {
    "sounds": [
      {
        "name": "my_pack:music/nether_ambient",
        "stream": true,
        "box": [10, 30, 10, 50, 80, 50],
        "dimension": "minecraft:the_nether"
      }
    ]
  }
}

2. Multi-Zones (box with an array of arrays)

The same track assigned to two different rooms. Walking between them will not restart the music.

{
  "music_disc.town_theme": {
    "sounds": [
      {
        "name": "my_pack:music/town",
        "stream": true,
        "box": [
          [-20, 64, -20, 20, 80, 20],
          [100, 64, 100, 150, 80, 150]
        ]
      }
    ]
  }
}

3. Presence Dependency & Looping (play_while_inside, next)

The music plays only while the player is inside the cube. Upon exiting, it smoothly fades out. The "next": "boss_theme" parameter forces the track to trigger itself after finishing, creating an endless loop.

{
  "music_disc.boss_theme": {
    "sounds": [
      {
        "name": "my_pack:music/boss",
        "stream": true,
        "box": [0, 60, 0, 30, 80, 30],
        "play_while_inside": true,
        "next": "boss_theme"
      }
    ]
  }
}

4. Creating a Playlist (next to a different track)

When track_one finishes, the mod automatically starts track_two.

{
  "music_disc.track_one": {
    "sounds": [
      {
        "name": "my_pack:music/part1",
        "stream": true,
        "box": [0, 60, 0, 10, 70, 10],
        "next": "track_two"
      }
    ]
  },
  "music_disc.track_two": {
    "sounds": [
      {
        "name": "my_pack:music/part2",
        "stream": true,
        "box": [0, 60, 0, 10, 70, 10]
      }
    ]
  }
}

5. Ignoring Note Blocks & Overlapping (ignore_note_blocks, allow_overlap)

This background hum can play concurrently with other music and will not become quieter if a note block mechanism is active nearby.

{
  "burosound.machine_hum": {
    "sounds": [
      {
        "name": "my_pack:ambient/hum",
        "stream": true,
        "box": [5, 64, 5, 10, 68, 10],
        "ignore_note_blocks": true,
        "allow_overlap": true
      }
    ]
  }
}

6. Exit Zone (exit)

This zone does not play music. If a player enters this corridor, any currently playing BuroSound music smoothly fades out and stops.

{
  "exit_corridor": {
    "sounds": [
      {
        "name": "none",
        "box": [30, 60, -5, 40, 65, -10],
        "exit": true
      }
    ]
  }
}

7. Block Click Trigger (block_trigger)

Instead of entering a zone, the music is activated by right-clicking a specific block.

{
  "music_disc.secret_button": {
    "sounds": [
      {
        "name": "my_pack:music/secret",
        "stream": true,
        "block_trigger": [10, 64, -5, "stone_button"]
      }
    ]
  }
}

Commands & Controls

For debugging convenience, the mod provides client-side commands:

• /burosound boxes Toggles the debug overlay. Displays colored outlines and labels for all active zones in your current dimension. Perfect for verifying coordinates.
• /burosound stop Instantly stops all playing BuroSound music and completely clears the queue of upcoming tracks.
