New in the Rolling Release: We've introduced master_me (a free and open-source audio post-processing tool) support as a first-class option in our web UI.
We've reworked our entire Post-Processing section of the station profile form to better explain what it does, to add more flexibility about where it applies, and to let you choose from several handy presets. If StereoTool is installed, you will also see it here and have the option to use it, but master_me will ship with all AzuraCast installs.
