The Realtek Audio Effects Component is a software driver package that is typically associated with Realtek audio hardware, such as integrated sound cards (often found on motherboards) or external Realtek audio devices. The driver provides the necessary software to enable and configure various audio features, including sound effects, equalizers, virtual surround sound, and other enhancements for the audio experience on a Windows system.

This component is often bundled with Realtek's HD Audio drivers and can be installed separately or automatically through the installation of the full Realtek driver package.
