This is Ennuizel, an audio editor for web browsers! You can find the main installation at https://ennuizel.github.io . Ennuizel is based on libav.js, which is in turn based on FFmpeg.
Although Ennuizel is perfectly usable as an interactive audio editor, its design intent is to be used as middleware for platforms providing other web-based audio systems. For instance, Ennuicastr uses Ennuizel to provide automatic mastering.
Ennuizel uses plugins to provide functionality, as well as to add "wizards".
The plugin API is documented in ennuizel.d.ts. Plugins do not have to be
written in TypeScript, but it is recommended. The better normalization
plugin is a
simple demonstration of how plugins work, and the Noise Repellent
plugin
demonstrates how to integrate non-FFmpeg filters.
ennuizel-ennuicastr-plugin
connects Ennuizel to Ennuicastr, and serves as en example of how to make a
wizard.
