Software Sound Level Meter
Menšík, Václav ; Sysel, Petr (referee) ; Schimmel, Jiří (advisor)
This thesis discusses noise measurement devices, design and implementation of a software sound pressure meter. Sound pressure meter requirements specified by the IEC 61672 standard and selected acoustic physical properties are discussed. Further, the JUCE framework is presented along with an of the graphical user interface and digital signal processing capabilities of the SoundMeter program.

Java Performance Testing For The Masses
Stefan, Petr ; Tůma, Petr (advisor) ; Hnětynka, Petr (referee)
Java is a major platform for performance sensitive applications. Unit testing of functionality has already become a common practice in software devel- opment; however, the amount of projects employing performance tests is substantially lower. A comprehensive study in combination with a short sur- vey among developers is made in order to examine the current situation in open-source projects written in Java. Results show that suitable tools for measurements exist, but they are hard to use or the outputs are difficult to understand. To improve the situation in favor of performance evaluation a set of user friendly tools for collecting, comparing and visualizing the data is designed, implemented, and verified on a sample Java project. 1
