SPECTRAL FEATURES OF THE CLARINET SOUND REVEALED BY THE SET OF STFT-BASED PARAMETERS
Tomasz J. Wilczy, Len Gelman, Piotr Kleczkowski · 2012
The analysis of time-frequency (t-f) spectra of musical instruments is commonly performed with the use of the STFT or other t-f analysis methods [13]. In order to gain more insight into this problem and to find out possible quantitative relations we used the STFT as a first step and then derived several parameters from it. These parameters were compared at various levels of instrument’s sound pressure. A quantitative analysis of the effect of sound level on the spectral features of the clarinet sound was performed. The clarinet was used by musicians to produce three levels of sound articulation, each resulting in a different sound level. Therefore, it was assumed that these ways of generation may affect the spectra. There seems to be no related literature, apart from an extensive study of the clarinet sound production presented in [2], including a virtual clarinet model.
