Analysis of Time-Varying Spectrum of Pianos
 Smělý, Pavel ; Rajmic, Pavel (referee) ; Jirásek, Ondřej (advisor)
This work focuses on an analysis of a time-varying spectrum of pianos. The beginning of the work deals with the gradual evolution of the piano, aiming at timbre and design, and it analyzes in detail its individual parts and their influence on the sound spectrum. The theoretical part also concentrates on the issue of harmonic analysis in both the musical conception of timber and the usage of mathematical signal processing methods that make this analysis possible. Another part deals with practical tasks of the work such as a description of an application and functions created in the interface of MATLAB for exploring the time-varying spectrum of tones, description of the method and procedure of the measuring of three concert grand pianos. The work also analyzes, by supporting it with practical examples and by comparing the measured pianos, the most important acoustic phenomena that originate from the production of tones in the instrument; it describes the timber of individual instruments, and it gives recommendations.

Analysis of Formant Areas During Sung Vowels
 Kukosa, František ; Švancara, Pavel (referee) ; Jirásek, Ondřej (advisor)
The study analyzes the formant zones of male voices in singing vowels with main focus on opera, chest and head vocal registers. The results of this work are based on the recordings of five singers, taken in an anechoic chamber. For the analysis of these recordings in the frequency domain were used the FFT algorithm and the LPC analysis. The results describe the nature of the individual registers and show the importance of the singing formants for singers. Especially for opera vocal register where the vocal formants, along with a natural vibrato technique, are very important.
