A method of building a database of timbre samples for music synthesizers is provided, which can help provide smooth transitions between adjacent looping waveforms in the looping segment of the synthesized sound waveform, and also help provide an optimal tradeoff between high timbre quality and low timbre vibrations. The method utilizes a cosine looping-waveform transformation function to obtain an optimized looping waveform that can be repetitively appended to the timbre sample with smooth transitions between adjacent looping waveforms such that the resultant synthesized sound waveform is free from ripples that will otherwise affect the reproduced timbre quality of the synthesized sound. Moreover, the method utilizes a timbre-balancing function that can help provide an optimal tradeoff between high timbre quality and low timbre vibrations. The reproduced timbre quality of the synthesized sound from the wave-table music synthesizer is thus very high.
