NOTE: 
Most sound files for musical instruments are meant for Fourier transform only. 

A signal that does not change in time is most often studied better by Fourier 
transform than by wavelet transform.

Even so, if you want to analyze the sound with wavelet transform, you may try 
to use the following parameters for analysis of the file "piano1Info.txt".


Nstart:	10000  **** NOTE: Try to analyze also piano2.wav (according to case1 in Info file)
N:	64k (1024*64)

fmin:	70.0
fmax:	6000.0

K:	20
