This is a quick-and-dirty reimplementation of reverb.nvim for Vim. Instead of an external command, it uses the built-in +sound API, and it's written in Vimscript. I don't intend to maintain it long-term, it's just here for Vim users to fool around with a cool idea.

Turn sounds on with: ReverbOn. Turn them off with ReverbOff. That's it.
You need Vim to be compiled with +sound, but most repositories have "huge" installations that should have it.
The sounds are in the sounds directory, and they might not match the exact ones used in the video, but they seem close enough. If you'd like to be able to customize these, feel free to open an issue, I can add some options. But you could also take a look at autoload/reverb.vim to how it's implemented, it's quite simple to connect an autocommand with a sound.
