How to set up:
This configuration file requires the plugin MagicSpells to run. Note that the 1.0.0 version of the Soundboard only includes sounds up to 1.12.2. That Minecraft version is only supported by MagicSpells versions below 4.0, which require EffectLib as well. The 1.0.0 version works on Minecraft versions 1.8.x-1.12.2, but you obviously can not play 1.12.x sounds on versions below. Soundboard versions above 1.0.0 support MagicSpells 4.0+.
Download the configuration file below and place the file in your MagicSpells plugin folder, then reload the plugin. To open use one of following commands: /soundboard, /sounds or /sb.
In the GUI you can search for sounds to check their sound names or select it to play it. You can modify pitch and volume and try what it sounds like with your configuration. Once you think the sound is good enough you can click the paper item to paste the current sound configuration in chat where you can copy it and paste it in your scripting plugin, or anywhere you need to use it.
