Attention! The answers are accepted only after the small test JOB: Website [login to view URL] - there's karaoke scoring program. It is necessary to install, run and get acquainted with its graphical user interface (including the song during playback). After that, arbitrary DESCRIBE it's GUI in C++ INTERFACES. The implementation (*.cpp) files are UNNECESSARY, only headers (*.h) containing class declarations with public functions and the representation (the data). The code may be simple but clear, with comments where appropriate. The class declarations must be valid C++ code. Problem. We need a C/C++ programmer who is familiar with FFT, and audio data processing. The work - the extraction of source code (algorithm), that performs scoring in performous, into a separate library. Setting up the code in accordance with the capabilities of the platforms on which the library will be used. program [login to view URL] test songs [login to view URL]
