Abstract
Proses analisa sinyal polyphonic merupakan dasar dari topik analisa sinyal. Pada
penelitian ini juga dibahas proses analisa terhadap sinyal musik. Instrumen alat musik yang
digunakan dalam penelitian ini ialah sasando. Sasando dipilih bukan hanya karena keunikkannya
dan karakteristiknya sebagai alat musi tradisional namun juga bertujuan dalam proses
pelestarian. Proses pelestarian terhadap alat musik sasando menjadi penting mengingat semakin
berkurangnya minat masyarakat untuk memainkan alat musik tradisional ini.
Penelitian ini menggunakan metode correlation. Metode ini membandingkan dua buah
sinyal untuk mencari kesamaan diantara kedua sinyal yang dibandingkan. Pada penelitian ini
dilakukan perbandingan terhadap sinyal polyphonic. Sinyal polyphonic yang dimaksud ialah
chord. Nilai kesamaan antara dua sinyal yang dibandingkan dapat dilihat dari karakteristik sinyal
hasil correlation. Karakteristik yang dimaksud berupa nilai amplitudo maksimum dan bentuk
sinyal hasil correlation.
============================================================
Polyphonic signal analyzing process becomes the basic topic of signal analysis currently.
Furthermore, analysis on the signal of music is also becomes the part of this topic. The main
chosen instrument is sasando. As the matter of fact, this is not only about its characteristic of
sound but also because of the need for the preservation of this musical instrument which is about
getting to be abandoned.
This research will apply cross correlation method. Cross correlation method will done
through signal comparing. We compare polyphonic signal (chord), which having multiple
fundamental frequencies. The compatibility can be obtained from amplitude score and signal
form characteristic as the result of cross-correlation process.
