This paper presents results of new wavelet coefficients tests and application to bassoon and French horn sound analysis. The coefficients were constructed based on musical chromatic intervals and applied to dilation equation to yield wavelet filter coefficients. Some examples compare results of recorded and inverse transformed signals showing the possibilities of their application to sound analysis of data segments of interest.
