Analog subtractive synthesizer
Jehlička, Maxim ; Mišurec, Jiří (referee) ; Vrba, Kamil (advisor)
This thesis deals with the design of monophonic analogue subtractive sythesizer. The sythesizer consists of MIDI to control voltage converter, voltage controlled waveform generator, voltage controlled amplifier, envelope generator, low frequency oscillator and voltage controlled filter.

Application for Demonstrating Principles of Hybrid Sound Synthesis
Prokop, Šimon ; Indrák, Michal (referee) ; Schimmel, Jiří (advisor)
The master thesis deals with the description and application of the main principles of sound signal generators contained in hybrid synthesizers. The individual methods and ways of generating audio signals were first studied and based on the theory, scripts were then created in Matlab to demonstrate the principle functions of the individual generators. Based on the logic of these scripts, a polyphonic hybrid synthesizer was created in VST3 format in the C++ language with the JUCE framework. The synthesizer allows the user to choose between basic readout methods Wavecycle and Wavetable, audio signal filtering or oversampling of the overall signal process.

Design and realization of ADSR filter
Pokorný, Martin ; Kratochvíl, Tomáš (referee) ; Slezák, Josef (advisor)
The master´s thesis is focused on design of ADSR filter and voltage controlled amplifier (VCA). Three additional circuits performing analog signal processing are added. Functionality of designed circuits is verified in simulation program. All designed circuits are practically realized. Thesis includes complete design of the mentioned circuits and all necessary informations for its practical realization. All designed circuits are measured and the results are presented.

FITkit Music Synthesizer
Melichar, Vojtěch ; Minařík, Miloš (referee) ; Vašíček, Zdeněk (advisor)
This bachelor's thesis deals with sound synthesis methods and with design of a synthesizer for FITkit platform. In the first part of the thesis, there are described methods of sound synthesis and the history of sound synthesis is also stated here. Next part contains a brief characteristic of sound chip SID 6581. In the next part of the thesis, there is a design of each part of the synthesizer: oscillator, envelope generator, voice and filter. Then, these components are put together to make up an synthesizer. Correctness of the implementation is verified by a simulation in ModelSim 6.6d. Individual components are simulated separately and then in mayor groups.

Synthesis of the musical audio signal using direct generation of harmonics
Ježek, Štěpán ; Mekyska, Jiří (referee) ; Přikryl, Lubor (advisor)
This thesis is focused on musical sound synthesis, in particular, the method of additive synthesis. The main goal is to implement a software musical instrument in the VST3 plug-in format, using the C++ programming language and the JUCE application framework. The final program offers spectral components editing capabilities and is able to morph between user-defined spectrum states in time. The introduction summarizes some common synthesis methods and their advantages or disadvantages. Next section deals with the technology used during the VST3 plug-in implementation and describes core parts that make up the final application. This analysis is focused mainly on the signal processing part, but there is also a brief description of the graphical user interface.

Experimental Hardware Musical Instrument
Chaňo, Petr ; Vrba, Kamil (referee) ; Dlouhý, Dan (advisor)
The main aim of the bachelor thesis was to design and build a musical instrument that will have a signs of the experimentalism consist of combination synthesizer and sequencer, tuning, unusual kind of controls and its look. At the top of this work is the theoretical introduction to the musical instruments and to the process of generating and modulating sound. There is also written information about parts that the instrument consists of (microcontroller, D/A converter), principles that leads to being able to create this instrument (operational amplifiers, frequency filters, DDS) in the theoretical part. The description of the components is in the practical part followed by the information about the circuits at this instrument and about software solution as well.

Deisign of the simple MIDI network
Lečbych, Jakub ; Krček, Petr (referee) ; Roupec, Jan (advisor)
The goal of this bachelor thesis is to compare advantages and disadvantages digital sound processing. Thesis is engaged in signal generating, editating, recording and mastering. It regards on the problem from the point of view of the sound designer, not like an artist. It also contains review of world-wide companies products. The aim of my bachelor thesis is to design a simple MIDI net, where audiosignal is generated and edited digitally, although output sound have characteristic warm abilities of analog synthetizer.

Experimental Hardware Musical Instrument, Converting Data from Sensors to Selected Musical Parameters
Šindler, Stanislav ; Kavan, Jan (referee) ; Dlouhý, Dan (advisor)
Abstract Aim of this thesis is to documentate theoretical and practical process of designing digital hardware syntetizer using Teensy microcontroler and add-on bus Teensy Audio Shield, with the help of Audio System Design Tool. Software for this synthesiser Product of this thesis will be complete device with user interface realized with rotational knobs, buttons and display unit. Also a removable module measuring temperature, intensity of light, and humidity, which will change user specified sound parameters, will be designed and constructed.
