prettyeq is a system-wide paramateric equalizer for pulseaudio. This software is in alpha. Use at your own discretion.

prettyeq demo


mkdir build
cd build
qmake CONFIG+=release ..
make -j4


When the program is executed all pulseaudio streams will be routed through the equalizer. With no filters activated prettyeq acts as a passthrough sink.

Right now prettyeq only supports two-channel sound.

Filter types

prettyeq has three filter types: * one low shelf filter mounted at 20Hz * one high shelf filter mounted at 20kHz * five peakingEQ filters that can move freely


Click and drag points to boost and cut frequency bands. The dB gain range is ±12dB. Filter bandwidth and slope can be changed with the mousewheel.


If your desktop has a system tray, the close button will hide the GUI but the equalizer will still be in effect. There are context menus in the application and tray that have a "exit" option to quit the application.
