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.

Audio signal dynamic compressors
Král, Vítězslav ; Kubánek, David (referee) ; Koton, Jaroslav (advisor)
The aim of this bachelor thesis is to get acquainted with the problems of analog compressors dynamics of the audio signal and practically verify one selected diagram. It deals with individual functional blocks compressor dynamics and shows examples of their implementation. Explains the characteristics of analog compressors and clearly justifies their importance. The thesis also describes the different topologies of analog compressors. Also discusses dynamic processors as such and summarizes their distribution by elementary principle and functionality.

VST Plug-in for Dynamic Processing of Audio Signal
Zoň, Robin ; Frenštátský, Petr (referee) ; Schimmel, Jiří (advisor)
The aim of this thesis is the implementation of effects for adjusting the signal dynamics. This project includes four basic dynamic effects - compressor, expander, limiter and noise gate. The first part is developed in Matlab software. This solution offers signal sidechain input, display of signal waveforms of each block of sidechain branch, recording output signal and allows storage of output characteristics. In the second part, the effect is being realized using VST technology, which offers the possibility of changing the parameters in real time and displaying and recording the signal at various points within the control branch. Project also includes a brief discussion of the use of such dynamic effects in practice and collection of model examples to demonstrate the use of such effects.

Analog Guitar Multieffect Using Tube for Signal Distortion
Kufa, Michal ; Kincl,, Zdeněk (referee) ; Staněk, Miroslav (advisor)
Presented thesis is oriented on the short survey of guitar effects functionality and the design of chosen guitar effects set embedded into one device. The first effect is related to input signal distortion using a vacuum tube, in this case the couple of double-diode tubes. Next effect is noise gate filtering parasitic artefacts included in input signal lower than set threshold level. The last realized guitar effect is chorus. Each individual effect can be controlled by footswitch. The first two sections are focused on the theory of guitar signal processing, the third section solves the whole design of chosen device, the realization and the proof of designed device functionality are described in further sections.

Digital Audio Signal Feature Extraction and Modification in Dynamic Plane
Kramoliš, Ondřej ; Sysel, Petr (referee) ; Schimmel, Jiří (advisor)
This thesis deals with basic methods of root mean square and peak value measurement of a digital acoustic signal, algotithms to measure audio programme loudness and true-peak audio level according to recommendation ITU-R BS.1770-1 and digital systems for control of signal dynamic range. It shows achieved results of root mean square and peak value measurement and results of implementation of dynamic processor with general piecewise linear non-decreasing static curve and algorithms according to recommendation ITU-R BS.1770-1.

Modification of Vocal Tracks in SW Post-Production of Music
Trkal, Tomáš ; Beran, Vítězslav (referee) ; Černocký, Jan (advisor)
This thesis describes a design and an implementation of a vocal tracks processing application. The application consists of several sub-modules representing audio processors and effects. It is implemented as a plugin created with the VST technology. The plugin provides a simple control system and an integrated database of presets which help mainly less experienced users to significantly speed up the process of processing the vocal tracks. The user evaluation shows that application is successful both in creating demos and professional mixing of music tracks.
