This is a trivial soundboard program that is controllable via a web browser, but plays the sounds on the computer where it’s running. I built this to use this in conjunction with discord-audio-pipe for my online RPG games, controlled from my iPad.
Get rust, cargo, etc. Then clone this repo, and:
cargo install --path .soundboard -d <directory full of audio files>
-d <another one, if you like>MIT; See LICENSE.
