Real-Time Sound Synthesis in Matlab

Goals of this paper are to create a programm which is able to use digital sound synthesis and play created signals in real time. Another goal is to create an environment for implementation real-time digital sound synthesis in Matlab controlled by MIDI protocol and to create tutorial how to programme a simple synthesizer in that environment. The paper shows basic theory for sound syntehsis methods. It describes MIDI protocol and how to process sounds in Matlab. It shows basic methods of sound synthesis in Matlab such as waveshaping, additive synthesis or subtractive synthesis. It presents ways how to achieve real-time synthesis controlled by external MIDI instrument. It presents programmable enviroment for real-time digital sound synthesis which works as Matlab audioplugin. The environment offers to play created sound signals in real time and controll parametres of synthesis by MIDI protocol. It also offers write signals down to file and show signal and its frequency spectrum in real time. As a part of this thesis an audioplugin was made which works as synthesizer using basic methods of digital sound synthesis. Another audioplugin was made as the environment for implementation digital sound synthesis. This audioplugin includes tutorial how to create simple synthesizer in this environment
