LRC7 is an Audio Unit, or AU, for iOS and macOS. This application is simply a container for the Audio Unit and serves only as the documentation. LRC7 must be used in some sort of Audio Unit host or DAW application. LRC7 is a seven-band EQ. It includes low shelf, high shelf, parametric peak/cut, notch, and various Butterworth low-pass and high-pass filters. Each of the bands can be configured to be any of the available filter types. Each band can also be turned off so that it passes the audio through unchanged, The frequency range for each of the filters is 10 Hz to 20 kHz. The filters aren't restricted to stay in any order. You can also set the "Q" factor of each of the filters. The value ranges from 0.0 to 1.0. The Q values behave differently in the different filter types.
