Method of designing families of boost and cut filters, including treble and bass controls and graphic equalizers

摘要

A simplified design for a family of bass, treble and graphic equalizer filters (20). The filter design allows on-the-fly implementation of these simplified filter types, even in audio systems without extensive computation resources. The methodology includes designing a nominal filter, and decomposing this nominal filter into a simplified transfer function such that the family of treble boost, cut, and equalizer filters can be realized with moderate computational resources.
