Raised Cosine Equalization
Raised Cosine Equalization is the foundation underlying Ideal Graphic EQ™ and Lake Mesa EQ™, the two revolutionary EQ interfaces provided by the Lake® Processor.
The graphic above shows boost shapes typical of raised cosine (blue) and conventional (red) equalization. Note the increased selectivity of the raised cosine shape.
The development of the Lake Mesa EQ was a significant advance in EQ technology. While other processors provide standard symmetrical boost and cut functions, the Mesa EQ offers asymmetric filtering, with the ability to separate the sides of a parametric section, change center frequencies, and independently adjust slopes.
The Mesa EQ gives sound engineers a faster, more effective optimization tool—one that can truly match the asymmetrical responses of loudspeakers.
