Digital filtering is one of the most important technology in the field of digital audio. Digital filter circuits have so far been applied to digital audio equipments for real-time digital signal processing. We think, however, no specific theory of systematic designing has been developed yet in this area. Authors have some experience in developing digital audio equalizer circuits by digital filter technology, which makes it possible to realize the desired frequency response, and also have developed, for application of these circuits, the digital audio mixer having three position equalizer on each channel. Then followed the development of 8-channel input, 2-channel output digital audio mixers as well as the designing theory and its applications, of which descriptions are given in this paper.
