In the same manner that a graphic equalizer can be converted into a dynamic EQ, a parametric filter can serve as the basis of a dynamics processor. As the parametric equalizer allows an engineer to focus on acoustic conditions rendering an audio source, integrating dynamics can yield a processor more applicable to issues encountered in audio production, as has been done in multiple specialized processors. A general dynamic parametric EQ can be applied to most, if not all, acoustic anomalies encountered in the recording studio. As most of these anomalies occur at outlying levels, threshold dynamics can control the anomalies while leaving normal levels untouched. We look at the architecture of a general dynamic parametric EQ and apply it to issues of instrument acoustics, room acoustics, and microphone setup acoustics in recorded tracks.
