Abstract:

This diploma thesis discusses methods of dictionary learning to inpaint missing sections in the audio signal. There was theoretically analyzed and practically used algorithms K-SVD and INK-SVD for dictionary learning. These dictionaries have been applied to the reconstruction of audio signals using OMP (Orthogonal Matching Pursuit). Furthermore, there was proposed an algorithm for selecting the stationary segments and their subsequent use as training data for K-SVD and INK-SVD. In the practical part of thesis have been observed efficiency with training set selection from whole signal compared with algorithm for stationary segmentation used. The influence of mutual coherence on the quality of reconstruction with incoherent dictionary was also studied.

Abstract:

The aim of this work is to design an architecture of the embedded device that will be used for controlling DAW software in recording studio. First of all, attention is given to a brief summary of the necessary knowledge which is needed to design such kind of device. Af- ter that follows short survey of the existing solutions and description of protocols which can be used for communication with the recording software. Then, subsequent part of the thesis builds upon these foundations and further elaborates the device architecture by me- ans of decomposing it into several modules. In fact, two hardware modules are designed and manufactured, when each of them is conceived on a separate PCB with its own microcon- troller. Then the control firmware has been implemented for each of the modules. At the end of the work an aluminium enclosure, which holds both modules, is designed. The result of this work is a functional prototype of the assembled controller which can be used for the purpose of controlling DAW software.

Abstract:

This Thesis deals with a method to enforce the intellectual property rights and protect digital media from tampering – Digital Audio Watermarking. The main aim of this work is implement an audio watermarking algorithm. The theoretical part defined basic terms, methods and processes, which are used in this area. The practical part shows a process of embedding the digital signature into a host signal and her backward extraction. The embedding rule used spread spectrum technique and a psychoacoustic model. The implemented psychoacoustic model involves two properties of the human auditory system which are frequency masking and representation the frequency scale on limited bands called critical bands. The model is relatively new and based on the DWPT. In terms of above model is then the digital watermark embedded in the wavelet domain. This algorithm is implemented in technical software MATLAB. One part of this work focuses on robustness tests of the algorithm. Common signal processing modifications are applied to the watermarked audio as follows: Cutting of the audio, re-sampling, lossy compression, filtering, equalization, modulation effects, noise addition. The last part of the thesis presents subjective and objective methods usable in order to judge the influence of watermarking embedding on the quality of audio tracks called transparency.

Abstract:

Different music performances of the same piece may significantly differ from each other. Not only the composer and the score defines the listener’s music experience, but the music performance itself is an integral part of this experience. Four parameter classes can be used to describe a performance objectively: tempo and timing, loudness (dynamics), timbre, and pitch. Each of the individual parameters or their combination can generate a unique characteristic performance. The extraction of such objective parameters is one of the difficulties in the field of Music Performance Analysis and Music Information Retrieval. The submitted work summarizes knowledge and methods from both of the fields. The system is applied to extract data from 31 string quartet performances of 2. movement Lento of String Quartet no. 12 F major (1893) by czech romantic composer Antonín Dvořák (1841–1904).

Abstract:

Several available free software audio solutions were analyzed, and Jackdmp—a C++ reimplementation of the renowned JACK Audio Connection Kit—was selected as the most appropriate solution for a real-time audio architecture on DROPS. The JACK sound architecture provides the lowest processing latency possible on a desktop computer for a given set of sound card parameters. It reduces the latency jitter caused by software to zero and synchronizes streams at sample accuracy. A real-time admission scheme for JACK clients is proposed. The execution time of different typical JACK clients was analyzed with measurements to validate the assumptions the proposal is based on, but also to gain further knowledge about their timing behavior. The measurements showed that the condition set by Paul Davis—the time to process a client must be a linear function of the buffer size—holds for all tested clients. Jackdmp was ported to DROPS. The developed design of the port and its implementation is documented here. Measurements showed that—although the real-time performance of the Linux kernel is continuously being improved in the mainline and on special external branches—DROPS can provide a signaling latency that is two times lower on average than the values that can be achieved on the same machine running with a low latency patched Linux kernel. Thus, it can be stated that DROPS is well-suited for real-time audio processing and that the pursued path to use it as the foundation of a truly real-time capable audio workstation should be followed
Wenn man heute digitale Audiotechnik zum Aufnehmen oder Abmischen von Musik oder anderen Audiodaten verwenden möchte, steht man vor der Wahl, entweder auf eine sehr spezialisierte Hardwarelösung zurückzugreifen oder aber sich eines gewöhnlichen Desktopsystems mit entsprechender Audiosoftware zu bedienen. Der Vorteil eines Desktopsystems ist neben seinem deutlich niedrigeren Preis vor allem die Flexibilität. Bezüglich seines Echtzeitverhaltens bietet ein Computer mit einem Standard-Desktop-Betriebssystem aber bei weitem nicht dieselbe Verlässlichkeit einer spezialisierten Hardwarelösung oder analoger Technik. Die Architektur von DROPS --- mit dem echtzeitfähigen Fiasco- Mikrokern auf der einen Seite sowie der Unterstützung von Legacy-Anwendungen durch L4Linux auf der anderen Seite --- birgt die Hoffnung, die Vorteile von den beiden eben beschriebenen Welten auf einem System mit DROPS kombinieren zu können. Die Motivation meiner Arbeit war es, für dieses langfristige Ziel einen ersten Grundstein zu legen. Dazu war es meine Aufgabe, verschiedene Open-Source- Lösungen hinsichtlich ihrer Eignung als Echtzeit-Audioarchitektur für DROPS zu analysieren und die am besten geeignete auf L4Env zu portieren. Meine Wahl fiel dabei auf das in der Linux-Audio-Szene wohlbekannte Jack Audio Connection Kit (JACK). Desweiteren konnte ich in der Arbeit untersuchen, wie sich die JACK Audioarchitektur in ein globales Echtzeit-Scheduling --- z.B. eines von DROPS --- einbetten ließe, und schlage eine generische Methode dafür vor

Abstract:

Over the last few decades, organizations have become increasingly dependent on information technology for the support of their business processes. IT has brought many benefits to the operations of organizations, as well as new risks. Internal control systems implemented to mitigate business risks thus needed to be extended to include a new group of IT controls. One of the areas of business operations that has been strongly associated with IT since the beginning of its widespread use is accounting. This master's thesis examines the effect of IT controls on financial statements of an organization as well as an audit of these financial statements. Principal aim of this thesis is to identify a set of IT controls relevant for a statutory audit. Emphasis is placed on controls covering the areas of information security, computer operations and change management related to information systems. A secondary aim is an analysis of control weaknesses (their nature and frequency of occurence) noted in the presented set of IT controls in a sample of statutory audits conducted in the last four years. For the most common control weaknesses, risks as well as possible causes are discussed and recommendations for improvement are provided.

Abstract:

Cloud computing brings to the world of information systems many opportunities but also new risks. The main one is decreased customer ability to directly control the security of information and systems, because administration responsibility passes to providers. This thesis focuses on cloud services auditing from the small and medium enterprises perspective. In introduction, this work defines information system audit terminology, characterizes cloud services and analyzes international legislation. Standardization organizations, published standards and methodologies that are widely respected in IT field are introduced. For the trust mediation in the cloud are important independent third-party audits and organizations specializing in the examination and control of cloud providers. The assumptions list is assembled on this basis to support screening process and to check, whether enterprise, service providers and services are ready for creating efficient and safe cloud system. The assumptions are applied to selected cloud service providers.

Abstract:

The aim of this master thesis is to evaluate the importance of audits of banks with respect to the Czech national economy within years 1993 - 2014. The primary purpose of this study is to determine the value of both external and internal audits as well as of internal control systems and of bank supervision in order to maintain a long-term stability of banks on the Czech financial market. In the light of knowledge gathered from the Czech banking crisis (late nineties of the 20th century) and from the latest widely-spread economic and financial crisis (2008), it has been proved that low-quality audits may consequently contagiously affect a great deal of financial institutions. As for the economies, a collapse of a larger number of banks in the short run may cause higher social costs (mainly due to government budget deficit when bailing out affected banks and to economic downturn). Analyses suggest that these crises have been a result of a confluence of many factors. In particular, a poor a management of banks and its interest in short-term profit-maximizing goals, trades with highly risky financial instruments (especially in the US and in the EU), likewise failures of both auditors and bank supervisors, account for some of the main factors. Moreover, it has been concluded that an institutional background (a weak law system in the Czech Republic) played an important role, too. The quality of audits was also influenced by an everlasting conflict of interest of statutory auditors who have been paid by the audited banks. This probably resulted in an unethical behavior of auditors. Furthermore, auditors were lacking the state-of-the-art knowledge in terms of rapidly developing financial instruments. As a matter of fact, auditors did not address all the risks the banks were facing to the stakeholders. This study indicates that both external and internal audits along with a bank supervision are important, nonetheless, not sufficient conditions assuring a long-term stability on financial markets.
