Experimental granular software with spatial setting
Pospíšil, Tomáš ; Dlouhý, Dan (referee) ; Indrák, Michal (advisor)
This thesis deals with a design and realization of the experimental software, which has the task to distribute the granular synthesis into surround sound, specifically into the octofonic sound system. The software is designed as a VST3 plugin, which was created in a JUCE framework. Apart of problematics mentioned above the thesis also contains theoretical and technical knowledge linked with granular synthesis, surround sound and a form of realization of a resulting software. The end of this thesis is dedicated to the testing phase and deficits of resulting software.

VST granular plugin with experimental input and output settings
Kalinič, Jan ; Dlouhý, Dan (referee) ; Indrák, Michal (advisor)
This thesis discusses the development of a plug-in module that is able to implement granular synthesis with help of experimental methods of parameter value settings. Graphic designs and schemes were created in the vector graphics editor Inkscape. The separate plug-in was programmed in C++ language using the JUCE framework and VST3 technology. With a use of this module, granular synthesis can be performed over a predetermined sample, but also over the stream of an audio channel of a digital audio station. The module also includes blocks with other types of sound synthesis, which can also be modified in experimental ways. Thanks to its properties, the plug-in can be applied as an effect over one sound channel in the mixing section of an audio station.

Sound Effect "Glitch Machine"
Cimmerman, Matej ; Mošner, Ladislav (referee) ; Černocký, Jan (advisor)
This thesis addresses software music effects and their implementation. It shows design and implementation of the Glitch Machine, which belongs to the music multieffect programs and demonstrates the simultaneous use of various music effects to process audio signals. The result is a program for Windows OS, which utilizes cooperation of various effects, namely a filter, reverb, distortion, extractor, reverz, stutter, shifter, pitch resample and gain. It allows extensive and detailed editing of an audio track and a higher extent of manipulation with sounds, than with single music effects. Other components of the program include visualisations of the waveform and frequency spectrum of audio signals and an option for loading and saving effect presets. The program was tested in tests of the performance and memory usage and also with user testing of quality and graphical interface.

Granular Synthesis in Music Production
Pečinka, Pavel ; Glembek, Ondřej (referee) ; Černocký, Jan (advisor)
Cílem této práce je navrhnout a vytvořit aplikaci pro granulární syntézu, využitelnou v hudbení produkci. Aplikace je implementována jako VST3 zásuvný modul s využitím frameworku JUCE a programovacího jazyka C++ a je schopná propojení s programy typu Digital Audio workstation, zkráceně DAW, což jsou programy sloužící jako centrální bod pro hudební producenty, kde mohou mimo jiné vytvářet nové zvuky, provádět mixování skladeb a vytvářet zvukové nahrávky. Tento zásuvný modul je navržen jako sampler a je schopen nahrát zvukový soubor obsahující audio data, která dále využívá pro další zpracování a následné přehrávání. Z vyhodnocení uživatelského testování vyplývá, že je tato aplikace použitelná pro hudební produkci jako nástroj pro granulární syntézu.

Implementation of Waveshaper Audio Effect
Leitgeb, David ; Miklánek, Štěpán (referee) ; Schimmel, Jiří (advisor)
The aim of this thesis is the implementation of a non-linear audio effect called waveshaper. This type of distortion effect contains the following building blocks: user defined transfer function, several types of filters and an oversampling processor with multiple stages of oversampling. The first prototype of this audio effect was implemented using Matlab and its Audio Toolbox extension. Due to certain limitations of this prototype, the whole audio effect was later completely rewritten in C++. This new implementation uses the JUCE framework which is mainly used for audio application development. The transition to this framework allowed real time editing of the transfer function and a VST3 build of the effect. In addition to a brief introduction of the used system types, motivation for oversampling and the description of the implementation for both prototypes, this thesis also includes graphical examples demonstrating their correct functionality. Audio files related to these examples are included in the electronic attachment.

Experimental Software Musical Instrument, Combining Step Sequencer and Sampler
Dobrocký, Filip ; Jirásek, Ondřej (referee) ; Dlouhý, Dan (advisor)
The aim of this thesis is to design an experimental software musical instrument combining a step sequencer and a sampler. The distinctive qualities of said instrument lie in the ability to produce complicated polyrhythms and make use of microtonality. The theoretical part of the thesis explores concepts such as polyrhythms, musical intonation systems, microtuning of electronic musical instruments, and explains the fundamentals of step sequencing and sampling. The practical part of the thesis features the design and implementation of the instrument, which takes form of a VST plug-in module implemented using the JUCE framework.

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.

Synthesis of Sound from Images
Zavřel, Petr ; Přinosil, Jiří (referee) ; Říha, Kamil (advisor)
This diploma thesis deals with the creation of sound from images. Before looking into the actual conversion of data, it takes into consideration the correlation between sound and images. Colour models of pictures used for the extraction of image data suitable for conversion into sound are examined here. Subsequently the work introduces methods for creating sound and changing its basic parameters. In order to present a suitable representation of sound, the work also explains the basics of music theory and methods of sound synthesis. The first part of the thesis offers two fully-fledged solutions using independent applications created in the MATLAB environment, where the basic principle is the division of the image into lines and the use of granular synthesis. The second part of the thesis describes the solution of the third application created in C++ language, where the emphasis is on adhering to the principles of music composition.
