Source Code: https://github.com/normano/jfxr
I forked JFXR and added electron support so one can open it as a native application.
JFXR is supposedly a spiritual successor to BFXR which one could use to create sound effects using waveform attributes and patterns. It's good stuff. While one could access JFXR online, there's no guarantee that will always be accessible. With this someone could put it on itch.io, but again no guarantee itch.io won't go to sh*t later. One could build the source code and just run the index.html, but why bother doing that everytime you want to run it hence the a Native App on your computer.
