Title: Resonance apparatus, resonance method and computer program for resonance processing

Abstract: Resonance is realized at a desired plurality of tone pitches even after the musical tone signals of a plurality of channels have been synthesized; synthesized musical tone signals are successively delayed, the musical tone signals that are successively delayed are weighted, synthesized and output; the delayed, weighted, synthesized and outputted musical tone signals are fed back, and a series of successive delays, weights, synthesizes and outputs by the feed back are repeated and thus resonance characteristics is imparted; the amount of weighting the musical tone signals successively delayed is determined based upon a relationship among the delay feedback period, the period of sampling the generated musical tone signals and the tone pitch period of the resonance sound imparted with resonance characteristics, and a frequency of the resonance characteristics are determined; Therefore, the resonance characteristics are added at a desired tone pitch after the plurality of musical tone signals are synthesized into one. Accordingly, the resonance processing is conducted very simply.
