Anotation:
This course introduces the fundamentals of sound synthesis algorithms (everyday, music and speech), digital audio effects and sonification. Multimedia synthetic signals are used in modern digital systems, virtual reality systems, computer animations, games and film. Understanding of theoretical concepts will be consolidated through practical programming assignments in Matlab.
Study targets:
Cílem studia je získání teoretických základů a praktického osvojení základních metod číslicové syntézy multimediálních signálů.
