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. And eventually the whole application was ported from GTK4 to
a combination of Qt, QML and KDE/Kirigami frameworks.

## 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.

If your distribution does not yet include packages required to build Easy Effects, Flatpak is a convenient option.

Easy Effects is designed assuming that your hardware stays as default device.
