Abstract :
In this paper, we present a technique to identify the scaling function and the wavelet functions of the wavelets present in musical instruments, violin and flute. We have used the NLMS algorithm to identify the filter bank coefficients of wavelet-like elements, found repeating in musical notes of the instruments. Scaling functions of the standard wavelets are also found out by an iterative manner using NLMS algorithm.
