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.

Simulations of auditory space and azimuth&distance of sound source, for multichannel sound systems
Orlovský, Kristián ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
This thesis is aimed at simulation of auditory space. It describes the most frequently used panning method: Vector Base Amplitude Panning. Also is focused on image source method, which allows computing the parameters of direct sound wave and reflections in rectangular room. This method is compared with ray–tracing method, which is also often used. It deals with the matter of the frequency – dependent absorption of materials in reflection of the sound wave against the wall. On the basis of these information two applications were designed in MATLAB development environment. The first one allows the simulation of auditory space. The other one is the application for sound source panning by its azimuth and distance.

Sound panning in multichannel sound systems
Orlovský, Kristián ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
This thesis is aimed at simulation of auditory space. The first part is based on theoretical information and explains two of the most frequently used sound panning methods: Vector Base Amplitude Panning and Ambisonics. It shows the ways for sound panning by these methods. In next step are methods compared based on theoretical information and simulations in Matlab environment and one most suitable method is chosen for using in second part. This part describes image source method which enables parameters computation of direct sound wave and optional number of early reflections in rectangular room. Also is focused on problem of frequency dependent reflections. In conclusion it offer knowledge obtained by simulation of different auditory spaces with different topology.
