Resonance apparatus, resonance method and computer program for resonance processing

A resonance method comprising:

• making generate a plurality of musical tone signals at a predetermined sampling period and synthesize these signals into one;
• making successively delay the synthesized musical tone signals, weight, synthesize and output the musical tone signals that are successively delayed, feed back the delayed, weighted, synthesized and outputted musical tone signals, repeat a series of successive above delays, weights, synthesizes and outputs by the feedback and thus impart resonance characteristics;
• making determine the amount of weighting the musical tone signals successively delayed 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 determine whereby a frequency of the resonance characteristics.

Computer programs for resonance processing comprising:

• processing for making generate a plurality of musical tone signals at a predetermined sampling period and synthesize these signals into one;
• processing for making successively delay the synthesized musical tone signals, weight, synthesize and output the musical tone signals that are successively delayed, feed back the delayed, weighted, synthesized and outputted musical tone signals, repeat a series of successive above delays, weights, synthesizes and outputs by the feedback and thus impart resonance characteristics;
• processing for making determine the amount of weighting the musical tone signals successively delayed 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 determine whereby a frequency of the resonance characteristics.
