About this Mod

A jukebox with a sculk shrieker and 2 noteblocks with sculk sensors overlayed with a 3D logo of the mod name

Use the magic of Sculk to connect Note Blocks to Jukeboxes as speakers.

Custom discs

Sculk Radio has native support for AudioPlayer by henkelmax.
Custom music discs from this mod can be used on a radio and will act the same as vanilla discs.

How to use

To start of, place a shrieker on a jukebox, to turn it into a radio.
When a jukebox is used as a radio it will not give off any audio itself meaning it can be hidden within redstone contraptions.

To 'receive' the signal sent by a radio, you need a speaker.
A speaker is made by placing a sculk sensor on top of a note block.
The maximum distance a speaker can receive a signal from is 16 blocks.

To expand the range of a signal you can repeat it using a signal repeater.
A single repeater is made by placing a sculk sensor on top of a block of amethyst.
The maximum distance for receiving and repeating a signal is 16 blocks. Which means a single repeater can already double the range of a speaker.

Things to know

  • Speakers and repeaters give of a redstone signal when playing/repeating audio. This means you can use them in redstone contraptions to trigger other things.
  • The max signal 'depth' is 8, which means a signal can be repeated 8 times making for a total max range of 128 blocks.
  • Radios and repeaters can each send to 8 receivers (speakers and/or repeaters).
  • Audio coming out of a speaker has the same distance and volume as if it came out of a jukebox.
  • Sculk blocks will not activate when they are part of a radio, speaker or repeater. Outside of these 'multiblocks' they have their vanilla behavior.

Experimental frequencies

The mod has an experimental feature that allows radios to send audio globally using frequencies.
This is disabled by default and can be enabled in the config file.

  • To set a radio's frequency, point a redstone signal into its Shrieker.
  • To set a speaker's frequency, it needs to have a Calibrated Sculk Sensor with a redstone signal pointed into its 'input'.
  • Only one radio can be on a frequency at a time, but multiple speakers can be on the same frequency.
  • If a radio is on a frequency, it will not connect to normal repeaters and speakers.

Configuration

On its own, the mod will not create a config file.
To change settings, you can install Fzzy Config.

To load changes to the config file, you can use the vanilla /reload command.

# Whether to enable the experimental version of global frequencies.
enableExperimentalFrequencies = true

Other Mod compatibilities

Mods that add new music discs and resource packs that change vanilla discs should also work natively. But be sure to create an issue on the Github if there are incompatibilities.
