Abstract

The purpose of this research was to analyze the sound of the Gong Ageng of Kagungan Dalem Gongso Kanjeng Kyai Guntur Sari. Based on the result of the analysis it was then synthesized a new signal to comprehend whether the analysis results were appropriate or not . The research was conducted by recording the sound of the gong by using Sound Forge software. The data of recording result were analyzed using FFT in order to obtain the sound signal components. The process of sound synthesis was conducted by using additive synthesis method supported by Matlab (R2012a) sofware. The results of this study showed that there were some basic factors which determined sound signal, which were fundamental frequency, harmonic frequencies, amplitudes, amplitude ratios and phase differences. The sound signal as the result of reconstruction from the data had been close enough to natural sound produced by the gong. The results of this study showed that the phenomenon of "ngombak" on the gong ageng was a beat between two frequencies that have a relatively high amplitude. Beside that, this study also showed that there were some fundamental factors that made up a sound signal that were the fundamental frequency, harmonic frequencies, amplitudes, amplitude ratios and phase differences. The sound signal reconstructed from the data above was good enough to approach the natural sound generated by the gong.
