The aim of the bachelor was to design a database structure for classification source code and implementations of digital audio effects algorithms. Classification criteria for these algorithms are described in the thesis. A new project can be added to the database using web form or via of the automatic classification. The automatic classification is called a function for automatic recognition information in source files. For this purpose a format of saving catalog information into the source file was designed. These saved data can be further recognized by the suitable algorithm which utilizes PHP standard functions and then they inserted into the database. The saved projects can be searched by the project name, author’s name, the project des...
