Software generator of test signals for acoustic measurements
Veselá, Petra ; Schimmel, Jiří (referee) ; Frenštátský, Petr (advisor)
The aim of the thesis is to create a VST2 plug-in module capable of generating input signals for different kinds of acoustic measurements. The opening section offers a theorethical overview of various test signals, their parameters and possibilities of their use during measurement. Subsequent divisions are then introducing a description of several methods of acoustic measurements and a brief overview of a VST interface. Last chapter offers the analysis of the created signals and discussion of their potential use in practice.

Simulation of analogue audio effecs using the nonlinear filters
Otoupalík, Petr ; Káňa, Ladislav (referee) ; Mačák, Jaromír (advisor)
This thesis deals with a simulation of analogue audio effects using the nonlinear models that replace the analogue nonlinear devices in discrete domain. The thesis describes Volterra system model and simplified Volterra system model that can be realized in two ways, either Wiener model, or Hammerstein model. The method for the analysis and modeling of audio and acoustic nonlinear systems is presented in this thesis. This method allows through knowledge of the input swept-sine signal and the response of the analogue nonlinear system to the input signal to determine the coefficients of the discrete nonlinear system. This allows simulating the analogue nonlinear system in discrete domain. The method was first tested and then used successfully for simulation of the analogue nonlinear system in discrete domain. Concretely, it was simulated a musical guitar effect of the type of distortion. Last part of this thesis is devoted a description of VST technology and an implementation of VST plug-in module, which realizations Hammerstein model.
