The Audition graphic filter file is a proprietary plugin format originally developed by Syntrillium Software for Cool Edit Pro and subsequently adopted by Adobe Systems. These modules function as internal components that enable specific audio effects, signal processing capabilities, and graphic equalization features within the digital audio workstation environment. As a legacy architecture, this format has largely been superseded by standardized VST and Audio Unit technologies, rendering it uncommon in modern audio production workflows.
