Influence of drivers position on the characteristics of the loudspeaker system
Bičan, Jan ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
This thesis deals with the measurement and description of properties of the two-way variable modular loudspeaker system marked as OM-3, especially the influence of the mutual position of drivers on its characteristics. The thesis examines individual factors taking their contribution on characteristics of the loudspeaker system in total. Further it measures and evaluates options of compensations of mutual position changes of drivers using an all-pass filter. Within this thesis is also included laboratory task preparation which is focused on this problematics.

Localization and Rendering of Sound Sources in Acoustic Fields
Khaddour, Hasan ; Rakús, Martin (referee) ; Husník, Libor (referee) ; Schimmel, Jiří (advisor)
Disertační práce se zabývá lokalizací zdrojů zvuku a akustickým zoomem. Hlavním cílem této práce je navrhnout systém s akustickým zoomem, který přiblíží zvuk jednoho mluvčího mezi skupinou mluvčích, a to i když mluví současně. Tento systém je kompatibilní s technikou prostorového zvuku. Hlavní přínosy disertační práce jsou následující: 1. Návrh metody pro odhad více směrů přicházejícího zvuku. 2. Návrh metody pro akustické zoomování pomocí DirAC. 3. Návrh kombinovaného systému pomocí předchozích kroků, který může být použit v telekonferencích.

Chorus effect - innovation of laboratory exercise
Zvončák, Vojtěch ; Schimmel, Jiří (referee) ; Říha, Kamil (advisor)
The thesis is a theoretical preparation and description of the construction of a laboratory device, which will be used in the laboratory of Studio and Musical Electronics course. At the beginning of the thesis there are basic features of effects with delay line explained. Then CHORUS effect and its mathematical function is desribed. Features of delay line are shown - delay line contains BBD shift register working on CCD principle. There are Frequency Response characteristics of CHORUS effect simaluted in VST Plugin Analyser program. Practical part deals with the description of the individual parts of the whole device circuit. Results of the significant signals measurement are introduced in chapter 5. A design of power switching supply for this laboratory device is presented at the end of the thesis.

Real-Time Analysis of Audio Signals
Řezáč, Martin ; Schimmel, Jiří (referee) ; Černocký, Jan (advisor)
The goal of this thesis is creation an application, which can perform real-time fundamental frequency tracking of incoming audio samples. According to detected frequencies, the program generates MIDI messages, which are sent to chosen MIDI device. First, the reader is introduced to the issue of fundamental frequency tracking. The following part describes individual methods, especially the one based on spectral analysis of a tone. A description of used technologies is also a included in this part of this thesis. In the following part, the implementation and testing of application are described including opinions of several musicians about this product. At the end, the whole work is concluded and the possible further development is outlined.

Design and Realization of Acoustic Treatments of Acouctic Space for Musical Production
Skvaril, Šimon ; Říha, Kamil (referee) ; Schimmel, Jiří (advisor)
Subject of this thesis are acoustical properties of space which is used for musical production and reproduction. It covers procedures, which are used for finding out acoustical parameters of chosen space, including virtual modeling and software simulation. Next, there are calculations and design of acoustical elements, which should help to improve quality of music listening. At the end those elements are created and applicated with their functionality verified by measuring acoustical properties

Wavefield Synthesis for Linear Loudspeaker Array
Panáček, Richard ; Balík, Miroslav (referee) ; Schimmel, Jiří (advisor)
This master thesis is meant to create a function for processing audio signals with Wavefield Synthesis for linear loudspeaker array. The text focuses on general issues of Wave Field Synthesis and practical design of 2.5D synthesis. It introduces Huygens’ principle followed by Rayleigh’s Theorem together with Rayleigh’s integrals. True design realizations are introduced based on theoretical procedures. The text states advantages and disadvantages of Wave Field Synthesis with linear loudspeaker array and also recounts solutions of some of the problems. The practical part of this thesis is devoted to designing two functions of Wave Field Synthesis inside the programming platform Matlab. The first function serves for processing signals from audio recordings and the second one for processing signals in real time. Proper functioning of procedures used in this thesis is then tested by a listening test.
