This application was formerly known as PulseEffects, but it was renamed to Easy Effects after it started to use GTK4 and
GStreamer usage was replaced by native PipeWire filters.

## Installation

### Distribution-specific packages

Most up-to-date Linux distributions have an `easyeffects` package that can be installed with the distribution package manager. See [the wiki](https://github.com/wwmm/easyeffects/wiki/Package-Repositories) for a full list.

### Flatpak

Alternatively, click here to install via Flatpak:

Flatpak packages support most Linux distributions and are sandboxed. The Easy Effects Flatpak package also includes all available plugins.
