The rationale of this research work was to find appropriate sound parameters on the basis of which it is possible to discern musical instrument sounds. A review of parameters used in musical acoustics was carried out focusing on the frequency-domain. Some of parameters were extracted from sound representations. Then, the quality of calculated parameters was tested statistically. Additionally, some discretization methods were applied in order to create so-called feature vectors that are to be used for feeding inputs of decision algorithms. Experimental results and conclusions are showed in the paper.
