LRC7, developed by Neon Silicon LLC, is an Audio Unit (AU) available for iOS and macOS platforms. This application serves as a container for the Audio Unit and acts as its documentation. It is essential to use LRC7 in conjunction with an Audio Unit host or DAW application.

With LRC7, users have access to a powerful seven-band EQ. The EQ features include low shelf, high shelf, parametric peak/cut, notch, and a variety of Butterworth low-pass and high-pass filters. Each band can be configured to any of the available filter types, allowing for a wide range of sound customization. Additionally, users have the option to disable individual bands, allowing the audio to pass through unaffected.
