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.

Experimental Software Musical Instrument on Android Platform Combining Sampler, Synthesizer and Sequencer
Kučera, Karel ; Kavan, Jan (referee) ; Dlouhý, Dan (advisor)
The aim of this bachelor thesis is the realization of the application as an experimental software musical instrument on the Android platform. The implementation is partly based on the draft elaborated in semester work. The application is designed for tablets and smartphones. It combines functions of sampler, sequencer and synthesizer and contains built-in effects. With this features, it is possible to create new sounds, sequantions and songs. The applications is programmed by visual programing language Pure Data. The graphic interface is created by the MobMuPlat platform. The thesis is consists of three parts. The first part is a theoretical introduction, where are discussed, the theory of digital audio signal processing, principles and types of sound signal synthesis, effects and electronic instruments. Furthermore, the Pure Data and MobMuPlat platform features. The second part is an updated design of the graphical interface and there are discussed the functions of individual graphic elements. The third part describes implementation of the application by Pure Data

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.

Experimental Software Synthesizer and Sequencer
Fadieiev, Heorhii ; Indrák, Michal (referee) ; Dlouhý, Dan (advisor)
This bachelor thesis is devoted to an experimental software synthesizer and sequencer. Its main goal is the realization of an experimental electroacoustic musical instrument based on a design created within the semestral thesis. The unique characteristic of this synthesizer is the possibility of assigning to each tone a different waveform from the field of subtractive synthesis, but also amplitude and frequency modulation, as well as the possibility of creating a complicated rhythmic structure. The work is divided into several parts. The first one deals with the collection of theoretical knowledge focused on the topic of sound synthesis, MIDI and software program Max. The second part of the work presents the design of an experimental instrument taking into account the block diagram of the synthesizer, its sequencer and generator. The next part of the work deals with the implementation of the instrument, describes its appearance, GUI, data storage in its memory and analyzes the patch of the synthesizer. The last part describes practical experience and general characteristics of the resulting instrument.

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.

Audio synthesizer in FPGA chip
Tomko, Jakub ; Pristach, Marián (referee) ; Bohrn, Marek (advisor)
This thesis analyses methods of sound synthesis. Advantages and disadvantages of application of individual methods in music synthetizers are evaluated. Based on piano sound analysis, the suitable method for synthesizer's design is chosen. Synthesizer has been implemented in FPGA of Spartan-3 Development Board.
