The Spectrum analysis of different types of saxophones
Greiplová, Barbora ; Mojdl, Edgar (referee) ; Jirásek, Ondřej (advisor)
The bachelor thesis deals with the sound of three types of Yamaha saxophones, specifically soprano, alto and tenor saxophone. Lists the basic parameters of the instrument, how it forms the tone and how it is typical. It focuses on characteristics in its tone using spectral analysis, LPC analysis and directional characteristics. The work focuses on the common properties of saxophones as instruments, it also looks for differences between selected types of saxophones and between individual tones. The results are compared in graphs, tables and verbal evaluation.

The analysis of the clarinet spectrum from different manufacturers
Suchánek, Tomáš ; Mojdl, Edgar (referee) ; Jirásek, Ondřej (advisor)
Bachelor’s thesis focuses on spectral analysis of six B clarinets made by manufacturers Buffet Crampon, RZ Woodwind Manufacturing and Yamaha. Instruments were tested by two professional musicians with different timbral preferences and the resulting spectrum is then applied to how psychoacoustic measurements define timbre perception. Furthermore, the impact of different dynamics or reeds is discussed and significant part of analysis also describes directivity patterns of individual higher harmonics or characteristic formant areas.

The Analysis of spectrum and polar pattern of French horn with different mouthpieces and different elastic resonators
Holba, Stanislav ; Ketner, Zbyněk (referee) ; Jirásek, Ondřej (advisor)
This bachelor thesis deals with the French horn and adjusting mouthpieces for this instrument. The work briefly describes the French horn, its structure, production materials, history and development, and the description of the timbre possibilities. Furthermore, the work explains the use of the fast Fourier transform algorithm in the context of analysis. A list of characteristics features of individual tools and mouthpieces used for analysis follows. The work then compares selected tone samples of natural and valve French horns from various manufacturers, their harmonic spectra, and directional characteristics. For specific tones, a list of chosen psychoacoustic quantities is given. The obtained values are linked with the mechanical characteristics of individual instruments and mouthpieces.

Spectrum analysis of the violin
Hanzálek, Pavel ; Smékal, Zdeněk (referee) ; Jirásek, Ondřej (advisor)
This work focuses on the problems of sound spectrum analysis and directional characteristics of the violin. The beginning of the work deals with the development of the violin, generally about timbre and directional characteristics. The theoretical part also deals with different types of sound spectra and LPC analysis on general. The practical part deals with practical tasks of work such as a description of the application created in MATLAB for examination of the time spectrum of tones, FFT spectra, formants by LPC analysis and display of directional characteristics. It also deals with the describing the methods, the process of sensing and measuring two different violins with different types of strings and age of corpus.
