Experimental Software Musical Instrument Controlled by Light Color
Liska, Matej ; Indrák, Michal (referee) ; Dlouhý, Dan (advisor)
Bachelor thesis contains the theory for realization of experimental software instrument controlled by light color. It brings knowledge of sound and light waves and color pro- cessing. Besides others, it describes process of generating digital signals using additive synthesis, methods of signal processing and sonification techniques. It solves program- ming possibilities of creating, processing, playing and saving digital audio signals. The audio source is written in Java language on the JavaFX programming platform.
The comparison of acoustic properties of guitars from the same product line
Trávníčková, Hana ; Indrák, Michal (referee) ; Jirásek, Ondřej (advisor)
This work is dealing with acoustic features of Furch guitars. In theoretical introduction is possible to find an information about basic characteristics of a tone. Following chapter about acoustic guitars is dealing even with mostly used types of woods for their manufacturing. In special chapter are described spectres of signals, LPC analysis, sound radiation of instruments and Chladni figures. Mentioned terms have been evaluated from measurements and are available in practical part of this work also including description of implementation of the measurement. As an output of this work is a comparison of acoustic features of measured guitars, their colours and modes.
The Influence of single harmonics or formants on timbre color perception
Klimeš, Martin ; Indrák, Michal (referee) ; Jirásek, Ondřej (advisor)
This thesis is dealing with the research of the influence of individual harmonic on the perception of sound color. An application was created with a questionnaire in which respondents assessed a total of 29 samples on different bipolar scales.The samples were either modeled by additive synthesis or created by modifying musical instruments. The aim was to investigate how and what combinations of higher harmonic affect the perception of sound color. The experiment is based on the semantic differential method. The samples were divided into several groups and within these groups they were compared and related to the expected color perception.
The spectral and directional analysis of xylophone, vibraphone and glockenspiel
Hoffman, Pavel ; Indrák, Michal (referee) ; Jirásek, Ondřej (advisor)
Bacherlor‘s thesis deals with spectral analysis and directional characteristics of idiophonic instruments, xylophone, vibraphone and glockenspiel. It analyzes various details during spectral analysis, that could have an effect on the spectrum of a given instrument, and especially on its inharmonicity, thus analyzing its effect on the hardness of mallet, dynamics and the location of the mallet striking the bars (stones, wooden plates). It examines the changes in the harmonic range and the formant areas of instruments. The thesis further describes the mallets, the instruments themselves, theoretical base and the means by which the sound samples were acquired and processed.
Experimental Software Musical Instrument Based on Granular Synthesis and its Spatial Distribution
Bateško, Tomáš ; Indrák, Michal (referee) ; Dlouhý, Dan (advisor)
The goal of this thesis is to create experimental software instrument based on granular synthesis and convolution, capable of spatial distribution of individual grains and ability to control them in real-time over network by multiple users simultaneously. Sound source is created in Pure Data and graphical interface was built using web technologies such as Node.js and p5.js
Digital Libraries in the Czech Republic and development of systems for production, dissemination and archiving of digital documents – ProArc, ARCLib and Kramerius
Lhoták, Martin ; Indrák, M.
Article discuss status of digital libraries and digitization activities in the Czech libraries and at the same time describes open source software tools for production, dissemination and archiving of digital documents - ProArc, Kramerius and ARCLib - developed in the Czech Republic by libraries.
Experimental Hardware Musical Instrument Combining Electronic and Electromechanical Sound Source
Pešán, Michele ; Indrák, Michal (referee) ; Dlouhý, Dan (advisor)
Student is to design and realize experimental electroacoustic hardware musical instrument; it can be find experimental because of its unusual quality of produced sound, extraordinary way of operating the instrument, or its looks.
Experimental Software Musical Instrument
Konečný, Dominik ; Indrák, Michal (referee) ; Dlouhý, Dan (advisor)
The goal of this document is a design and realization of a synthesizer combining additive and subtractive synthesis in Max/MSP. The synthesizer will distinguish itself from others with its high variability of amplitude envelopes, low frequency oscillators (LFO) and an option of micro interval tuning and inharmonious spectrum. There will also be an option to setup the parameters by typing a text string.
The Complex evaluation of financial situation of the Coca-Cola HBC Česká republika spol. s r.o.
Indrák, Martin ; Boukal, Petr (advisor) ; Kerel, Roman (referee)
The Purpose of this thesis is to briefly describe the company but also the whole branch of soft drinks production. The Dissertation investigate financial structure and analyzes the company through particular instruments of financial analysis such as absolute and ratio indexes, Du Pont decomposition, Altman index, Model IN and Economic value added. Also comparison with the biggest and most dangerous competitors on the market is the other essential part. Output of this thesis presents the evaluation of the financial health and condition of the company, its market position and last but not least some little recommendations, if needed.
