Frequency-warped signal processing for audio applications

Modern audio techniques, such as audio coding and sound reproduction, empha size the modeling of auditory perception as one of the cornerstones for sys tem design. A methodology, frequency-warped digital signal processing, is p resented in a tutorial paper as a means to design or implement digital sign al-processing algorithms directly in a way that is relevant for auditory pe rception. Several audio applications are considered in which this approach shows advantages when used as a design or implementation tool dr as a conce ptual framework of design.
