Abstract
A system for timbral change, capable of changing timbres included in an existing music audio signal to arbitrary timbres. Replaced harmonic peak parameters are created by replacing a plurality of harmonic peaks included in harmonic peak parameters, which are stored in a separated audio signal analyzing and storing sectionand indicate relative amplitudes of n-th order harmonic components of each tone generated by a musical instrument of a first kind, with harmonic peaks included in harmonic peak parameters, which are stored in a replacement parameter storing sectionand indicate relative amplitudes of n-th order harmonic components of each tone generated by a musical instrument of a second kind and corresponding to each tone generated by the musical instrument of the first kind. A synthesized separated audio signal generating sectiongenerates a synthesized separated audio signal for each tone using parameters other than the harmonic peak parameters and the replaced harmonic peak parameters.
