Raised Cosine Equalization Utilizing Log Scale Filter Synthesis

Document Thumbnail

An improved method of audio equalization utilizing Raised Cosine Filters is introduced. Raised Cosine Filters offer improved selectivity in comparison to traditionally implemented equalization functions, while also maintaining beneficial attributes such as a minimum phase response. The Raised Cosine Filter also enables flat summation and asymmetrical filtering characteristics, resulting in an equalization system offering capability beyond traditional filter implementations.
