Easy Effects is a user-friendly audio effects application formerly known as PulseEffects. Easy Effects offers an array of effects including Auto gain, Bass enhancer, Compression, Convolution, Delay and many more. The application is highly customizable and the user has full control over the effects order. It is available through most Linux distribution packages or via Flatpak, which includes all available plugins. It is important not to set Easy Effects’ virtual devices as your default audio input/output. The application comes with comprehensive help pages but if help pages are inaccessible, installing the yelp package is recommended. Donations towards further development are welcome.
