Abstract

Modern digital audio techniques, such as audio coding and sound reproduction, emphasize the importance of auditory perception as one cornerstone for system design. This paper presents a methodology, frequency-warped signal processing, as a means to design or implement DSP algorithms directly in a way that is relevant for auditory perception. Several audio applications are considered, in which this approach shows advantages when used as a design or implementation tool or as a conceptual framework of design.:
