Sound source panning in non-standard speaker topologies
Doležel, Roman ; Balík, Miroslav (referee) ; Orlovský, Kristián (advisor)
This work is aimed to sound source panning in two-dimensional space. The first part describes sound sensation by human auditory organ and spatial hearing. Next aim of the work is to describe commonly used panning methods VBAP and Ambisonics and newly introduced method DBAP, which is the main subject of this work. All methods are explained based on theoretical information. The third part of the work deals with knowledge of the amplitude method DBAP obtained by simulation in Matlab for various speakers topologies. The last section is focused on listening tests for comparison of methods DBAP and VBAP.

3D Audio Standards in Home Theatre Environment
Kováč, Daniel ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
This work deals with object-based sound. There is a description of the difference between channel-based and object-based sound and the development of this sound to today's form. Subsequently, formats that work with objects are described, and they are compared with each other. MPEGH-3D Audio format is specified here, which is a standard today, and also the method of positioning the virtual audio source by vector-base amplitude panning. It also describes how an encoder and decoder supporting speaker configurations 5.1.2, 5.1.4 and 7.1.4 has been developed according to the MPEG-H 3D Audio specification. Lastly, the work deals with the problem of panning the object sound to the standard configuration and there is also a mention of the listening test.

Simulation of sound source motion for multichannel speaker topology
Dvořák, Petr ; Kurc, David (referee) ; Orlovský, Kristián (advisor)
This paper describes the simulation of the motion of a sound source in space with several speakers. It deals mainly with the study and subsequent implementation of events necessary for simulating the motion of the virtual sound source. The theoretical part is therefore concerned with finding these phenomena and with their description. Mainly that means description of panning of the sound and of the Doppler effect. In the following practical part of the work, the previously described phenomena are applied into Matlab. In the created interface , it is then possible to select the parameters of the simulation, such as the trajectory of the motion of the virtual sound source, the number of the points of the trajectory, etc. Analyses of the generated signal are then made of the selected referential parameters of the simulation.
