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.

Analysis of the spectrum of cymbals and their time envelopes
Adamják, Adam ; Musil, Jaroslav (referee) ; Jirásek, Ondřej (advisor)
This Bachelor Thesis deals with the analysis of idiophones, the description of the measuring chain, and the analysis of the spectrum and time course of the measured samples. Based on spectral analysis, individual parameters and influences on the sound of cymbals were evaluated, such as the location of the blow or the type and hardness of the drum sticks. The theoretical basis also deals with the basic theory of the sound signal to the issue of noise and psychoacoustic perceptions. The conclusion deals with the basic mechanical properties and puts them into context with spectral analysis.

The Spectrum analysis of different single drums from a drum set differently tuned and played by different drumsticks
Cvetler, Dominik ; Mojdl, Edgar (referee) ; Jirásek, Ondřej (advisor)
The bachelor thesis deals with the analysis of the spectrum of membranophones, more precisely drums from the drum kit. Spectrum analysis evaluates aspects that affect the instrument’s spectrum, especially its inharmonicity and the generation of noise or tone modes. The aspects examined are the impact of the drumsticks hardness, the impact hit point on the drum membrane, the tuning of the resonance membrane and the presence of the tailpiece. The thesis examines inharmonicity in the spectrum with harmonic ratios between individual components in bands of harmonic series. The thesis also describes individual drums in terms of organology, drumsticks and membranes used for drums, the theoretical basis of creating membranophones sound and the way in which the measured samples were recorded and processed.

The Spectrum and ADSR analysis of different kinds of harpsichords
David, Václav ; Peloušek, Tomáš (referee) ; Jirásek, Ondřej (advisor)
The work deals with the issue of temporal analysis of the variable frequency spectrum of the harpsichord and its amplitude envelope in time. In the introduction, the creation is described, what type of instrument the harpsichord is, the history of the instrument is also described, and above all, the construction and principle of tone are described. In the following part, we deal with the measurement of the output signal itself, followed by its spectral analysis, where the topic of sound color and the behavior of the harmonic series of the tone are discussed. The formation of inharmonicity in individual registers of the harpsichord is being examined, and the last subchapter focuses on the sharpness of tone over time.
