The standalone filter can be used to influence any parameter in an AE composition, and it has a somewhat different workflow and has its own Help file document.
The BCC product also includes a BCC Beat Reactor standalone filter found in the BCC Time filter category. This graph can be used to help target particular elements within the audio track for use in influencing other effect parameters. Beat Reactor displays a spectrum graph including vertical bands representing the audio levels within various frequency ranges. Beat Reactor is a parameter group found at the bottom of some BCC and FEC filters which can be used to influence other effect parameters within the filter based on an audio track within the composition.
