Spring reverb
Hroch, Matěj ; Dvořák, Jan (referee) ; Kubánek, David (advisor)
Bachelor thesis deals with design of analog reverb effect. Specifically, it deals with effect, where the reverbation is simulated by spring reverb tank. Thesis contains design of excitating and sensing circuits, also impedance and transmission features measuring. Final device should be compatible with common used audio devices. Reverb design is improved by adding noise gate and feedback. The thesis contains desingn of PCB and whole device construction. Features measuring is also contained. For retro design, VU meters circuits are added. The thesis contains already known circuits, which were tested and improved.

Design and Realization of Modification of Acoustic Field in Laboratory
Ješko, Petr ; Rášo, Ondřej (referee) ; Schimmel, Jiří (advisor)
The thesis deals with the problems of closed spaces. It deals with situations where it is necessary to reduce the reverberation time in certain octave bands. It provides procedures comparing conventional method of solving by calculation of the mean sound absorption coefficient of the area and the subsequent experimental addition of acoustic absorbers which occupy different areas and method that uses an acoustic simulation software for the 3D model. It also deals with a concept of Reflection Phase Grating diffuser.

Design and Realization of Acoustic Treatment of Small Recording Studio
Tkadlec, Vojtěch ; Husník, Libor (referee) ; Schimmel, Jiří (advisor)
This bachelor thesis deals with the topic of acoustic properties of an enclosed space, their detection and modification. The thesis examines the acoustic properties of a small enclosed space, which were determined by simulation using a virtual 3D model and subsequently verified by measurement. After finding out the properties, a substantial part was also devoted to their modification, where the task was to design the acoustic elements so that the resulting length of the reverberation time corresponds to the optimal values for a small recording studio. The design of the elements is followed by their construction, followed by a re-measurement of the space. Furthermore, the work summarizes the principles of modeling and simulation of 3D models.

Software Multi-Effect for Post-Production of Pop Music
Trkal, Tomáš ; Glembek, Ondřej (referee) ; Černocký, Jan (advisor)
This diploma thesis deals with design and implementation of complex software system for post-production of popular music. The system was implemented as a plug-in module in C++ language using JUCE application framework. The emphasis was on creating a well arranged and intuitive graphic user interface. The plug-in provides a set of audio effects and processors that can be connected into the desired graph structure. For less experienced users, there is a database of preset configurations usable for a variety of input signals.

Spectral analyse of sound in space acoustics
Port, Martin ; Bereznanin, Martin (referee) ; Rozman, Jiří (advisor)
This thesis is an introduction to the problems of acoustics and is focused on the variables describing the noise. The methodology for measuring noise in relation with valid hygiene standards is analyzed in next section. The noise levels at work required by government regulation no. 148/2006 are summarized in a subsequent charter. The next section is an introduction to the analyzer PULSE 3560B from Brüel & Kjar. This work describes a software called Labshop, which is designed to analyze noise and vibrations. It also describes the most common features Acoustilyzer NTI AL1. The practical part was to measure the reverberation, noise, frequency spectrum and plott the distribution of noise with noise maps of various auditoriums.
