Abstract :
The optimal filter length of linear prediction (LP) model of musical signals are compared with speech signals in the paper. These musical signals are single musical instruments and vocal. Firstly, the global and segmental optimal orders of LP model are defined then the global optimal orders of LP model are measured for appropriately chosen musical and speech signals and finally statistical tests are performed. These tests determine if the differences between measured optimal orders are statistically significant or not.
