Abstract

This paper describes a software tool developed in the Java language to facilitate time and frequency warping of audio spectra. The application utilises the Java Advanced Image Processing (AIP) API which contains classes for image manipulation and, in particular, for non-linear warping using polynomial transformations. Warping of spectral representations is fundamental to sound processing techniques such as sound transformation and morphing. Dynamic time warping has been the method of choice for many implementations of temporal and spectral alignment for morphing. This tool offers greater advantage by providing an interactive approach to warping, thus allowing greater flexibility in achieving a desired transformation. This application can then be used as input to a signal synthesis routine, which will recover the transformed sound.
