Comparison of Algorithms for Creation of Artificial Room Reverberations
Beňo, Tomáš ; Balík, Miroslav (referee) ; Frenštátský, Petr (advisor)
The aim of the Bachelor thesis is to get acquainted with and find out possibilities of control of the reverberation properties of established algorithms for creation of artificial room reverberation. The algorithms proposed by Jon Dattorro, William Gardner and Jean-Marc Jot are implemented in the Matlab environment. Their characteristics and comparison are determined. Subsequent implementation of Jot's algorithm into the VST plug-in module in Matlab using the Audio System Toolbox extension enables to study the properties and behavior of the algorithm that handles real-time sound. The resulting plug-in can then be tested in DAW as a host application.

Multiplatform audio player
Malár, Ladislav ; Mach, Václav (referee) ; Sysel, Petr (advisor)
This master thesis deals with creating of the cross-platform audio player with the possibility of its use in the speech-language pathology clinic. The theoretical part is focused on the comparison of two multi-platform libraries, of which was one chosen for creating of the player. Subsequently on functionality SQLite database, which was also used as part of the final application. The basis of the practical part is the creation of the cross-platform audio player which is extended about database of patients and also extended about speech signal analysis with the help of VST plugin.

Digital audio effect based on wavelet transformation
Mikl, Martin ; Schimmel, Jiří (referee) ; Rajmic, Pavel (advisor)
The Bachelor's thesis deals about problems of digital signal processing. The first part includes function and use of VST Plug-In standard. It describes the history of the VST Plug-In interface, its use in hosting programs, there are a few words about another similar technologies and license terms of use. It is also briefly described the principle of wavelet transform, including some basic mathematical equations. Emphasis is placed on the Discrete-time wavelet transform and Fast wavelet transform. The knowledge of the wavelet transform led into concept of a block diagram with digital audio effect. From this concept has been made digital audio effect in VST Plug-In standart. The final part describes the solution of this effect, including analysis of its component functions. It describes the transmission of the important variables and its controls.

Sound Creation Using VST
Švec, Michal ; Schimmel, Jiří (referee) ; Černocký, Jan (advisor)
This diploma thesis deals with digital sound synthesis. The main task was to design and implement new sound synthesizer. Created tool uses different approaches to the sound synthesis, so it can be described as a hybrid. Instrument design was inspired by existing audio synthesizers. For implementation, C++ language and VST technology from Steinberg are used. As an extension, a module, that can process voice or text input and then build a MIDI file with melody (which can be interpreted with using any synthesizer) was designed and implemented. For this module, Python language is used. For the synthesizer, a simple graphical user interface was created.

Audio effect for pitch modification
Čermák, Václav ; Sysel, Petr (referee) ; Schimmel, Jiří (advisor)
This thesis deals with the realisation of an effect for real-time pitch detection and pitch shifting. At first, properties and basic operations of audio signals are analyzed for time and frequency analysis. An emphasis is placed on signal conversion from the time domain to the frequency domain. Methods for audio pitch shifting, fundamental frequency detection and voiced parts determination are discussed next. The practical part describes design of relevant algorithms, their implementation in Matlab environment and evaluation of the results. Evaluation is followed by the creation of a VST plug-in for real-time pitch shifting, which contains chosen algorithms from the previous section and is the final output of this thesis.
