Establishment of database of musical instruments recordings
Lavický, Vojtěch ; Mácha, Tomáš (referee) ; Rášo, Ondřej (advisor)
In this Bachelor thesis you can find created database of musical instruments. Recordings are descripted by it's waveforms and sectrograms. It may serve for example for removing noise from signal. A general data of instruments are descripted here. Human earing and his perception of sound is discuss here. There are also included parameters of sound itself and theory of calculations. Frequency and dynamic range are written to every instrument in database. These are consequently range by its size. As a part of the thesis is program with graphical user interface. The program include all the recordings from database and is open to any other recordings.

Tool for Automatic Subtitle Alignment
Chudý, Daniel ; Chlubna, Tomáš (referee) ; Milet, Tomáš (advisor)
The main motivation of this work is to simplify the retiming of subtitles, where the inputs are the original and edited video files and subtitles corresponding to the original video. Example – a video editor needs to cut a scene from a video. Subtitles that correspond with the clipped part of the video must be manually removed and the subtitle part that follows the clipped part must be manually re-timed. The tool makes this work easier by automating it. From an arbitrarily edited version of the video file (cuts), the original file and the original subtitles, a version of subtitles will be created that fits the edited version of the video file. Simply put, the goal is to align the original subtitles with the edited video file. The solution is the conversion of video files to audio files (.wav, wavfile), extraction of MFCC (Mel-frequency cepstral coefficients) and subsequent mutual comparison with the Dynamic Time Warping (DTW) algorithm. From the alignment path (DTW output), signal differences (cuts in the video) are detected and subtitles are adjusted based on them. A dataset was created to test the application consisisting of public domain films and own recordings. The created application provides 69 – 90 % subtitle alignment success on a dataset that contains videos of length 1 – 60 minutes.

Sound Effect "Glitch Machine"
Cimmerman, Matej ; Mošner, Ladislav (referee) ; Černocký, Jan (advisor)
This thesis addresses software music effects and their implementation. It shows design and implementation of the Glitch Machine, which belongs to the music multieffect programs and demonstrates the simultaneous use of various music effects to process audio signals. The result is a program for Windows OS, which utilizes cooperation of various effects, namely a filter, reverb, distortion, extractor, reverz, stutter, shifter, pitch resample and gain. It allows extensive and detailed editing of an audio track and a higher extent of manipulation with sounds, than with single music effects. Other components of the program include visualisations of the waveform and frequency spectrum of audio signals and an option for loading and saving effect presets. The program was tested in tests of the performance and memory usage and also with user testing of quality and graphical interface.

FPGA Module for Fast Waveform Generation and Synchronous Data Acquisition
Eliáš, Josef
This article deals with system for fast waveform generation and synchronous data acquisition. System is used for evaluation of optical sensors by sweep through narrow band light source. The DAQ system use dual core ARM processor with build in FPGA array. We can achieve direct sharing memory between ARM core and AD/DA periphery through SoC architecture. Then we can optimally distributed core usage between processors and peripherals.
