Audio Synth

by HiBer2007

Audio Synth adds a block that generates sound from waveforms, with frequency modulation, redstone control and range-based attenuation.

ForgeNeoForgeClient and serverGNU Lesser General Public License v2.1 or laterOpen source1.20.1 – 1.21.1

What it does

The synth block produces tones from several waveforms: sine, square, triangle, sawtooth and white noise. Frequency modulation is supported with an adjustable modulation depth and frequency. The mix output factor is reserved for future use, so the current version uses a single waveform at a time.

Each block has its own decibel gain setting, from -60 dB to +60 dB, and a configurable propagation range in blocks. Beyond that range the block is silent, and volume falls off with distance inside it. A redstone signal starts playback and stopping the signal stops it. A global volume multiplier is set in the mod's configuration screen, reachable through the Mods menu Config button or by editing the config file directly.

Both the server and every player need the mod. Files are published for Forge and NeoForge, with 1.1.2 for 1.20.1 as the latest Forge build and 2.0.0 for 1.21.1 as the latest NeoForge build. The code is released under the GNU Lesser General Public License v2.1 or later, and the source and issue tracker are public.

Key features

  1. Multiple waveforms

    The synth block generates sine, square, triangle, sawtooth and white noise waves.

  2. Frequency modulation

    Modulation depth and frequency can be adjusted to shape the sound produced by the block.

  3. Per-block volume and range

    Each block has its own decibel gain from -60 dB to +60 dB and a configurable propagation range with distance falloff.

  4. Redstone activation

    A redstone signal starts playback, and removing the signal stops it.

Use cases

Sound in builds

Synth blocks placed around a build can produce tones that carry only as far as their configured range.

Redstone-driven audio

Circuits can switch the synth on and off, so sounds start and stop with the redstone logic.

Who it’s for: Players who want audible redstone-controlled tones in their builds, and server owners who want the same synth behavior for all players.

Questions

Does Audio Synth need to be installed on the server?

Yes. Both the server and every player need the mod, since it runs on client and server.

Which loaders does Audio Synth support?

Forge and NeoForge. Files exist for 1.20.1 on Forge and for 1.21.1 on both loaders.

Does Audio Synth change its recipe when Create is installed?

Yes. The block recipe adapts depending on whether the Create mod is installed.
