RPG Maker Plugin for Audio Convolution

What Is This?

This plugin allows you to use audio convolution to make your existing sounds & music sound as if they're being played in small, cramped rooms, huge, echo-y caves, or anywhere else you can imagine!

How to Use

I've put together a 10 minute YouTube video which demonstrates the plugin, explains how to use it, how it was made, and where you can find many-many free effects to use with the plugin!

tl;dw:

1. If you're using RPG Maker MV, use the contents of the MV/ folder; if MZ, MZ/!
   
2. Place the contents of the js/plugins folder in your game's js/plugins folder
3. Place the contents of the audio/convolver folder in your game's audio/convolver folder
   • Yeah, that's probably a new folder for your project!
4. There are two plugins (the second is technically optional, but you probably want both):
   1. bentelk_AudioFilters
   2. bentelk_AudioFiltersMapHelper (must be loaded after the first)
5. Use notetags in your maps to apply audio convolution to the types of sounds you want, on that map, ex:
   • <filterbgm: echo>
   • <filterse: muffle>
6. See each plugin's help for more information and ways to use these plugins!

Finding & Making New Effects

The plugin comes with echo and muffle effects - called "impulse responses" - but you can find many other effects online, for free, or even record your own!

• Search "impulse response" on freesound.org (hundreds of results!)
• Search "create impulse response" on YouTube

How it Works

Audio convolution is a feature built in to browsers, and even desktop/downloaded RPG Maker games run on a small, isolated browser. This plugin taps into that built-in feature, and exposes it to RPG Maker.

There are a few tutorials online for how to use audio convolution within the browser; I happened to use this one when making this plugin:
