Frequency-Warped Signal Processing for Audio Applications

摘要

Modern audio techniques, such as audio coding and sound reproduction,emphasize the importance of auditory perception as oneof the cornerstones for system design. In this article we present amethodology, the frequency-warped digital signal processing, as ameans to design or implement DSP algorithms directly in a waywhich is relevant for auditory perception. Several audio applicationsare considered in which this approach shows advantages whenused as a design or implementation tool or as a conceptual frameworkof design.
