A platform for digital reproduction sound of traditional musical instrument kompang

摘要

This work proposes a system for the digital reproduction sound of kompang. Thekompang sounds are represented by bung and pak produced by palm beating to the membrane. Thesounds are recorded in an acoustical sound recording system. In this proposed system, the recorded sounds are then analyzed in a frequency analyzer SpectraPLUS. This frequency contents data can be used as the reference to check the reproduced digital sound. The recorded wave data is converted to MIDI format before being manipulated in Ableton synthesizer system to create modern keyboardnotes but representing kompang sound. For the validation purpose, a subjective approach as an additional to the objective comparison with frequency contents is also proposed.
