Borneo Lute ‘Sape’: The Frequency Spectrum and Time Frequency Analysis (TFA)
BioResources, 2023 Sound elements were studied for a six strings sape, a traditional instrument. The frequency was evaluated using a frequency spectrum and a time frequency plane. PicoScope oscilloscopes and Adobe Audition version 3 were used to record the acoustic spectra.
