Technologies and implementations of audio plug-ins

Music accompanies people throughout our entire evolution. As man has evolved, so did music and technology for its creation. Nowadays, recording and producing music is dominated by digital audio workstations and various digital software, which allows fast, easy and high-quality manipulation of audio signals. In this diploma thesis I dealt with the audio plug-in technology that enables the creation of various sound effects and also sound reproduction. The vast majority of its implementations is based on various analog devices, which have been used on different musical recordings, which marked different musicians, as well as various musical periods. In the first part of this thesis I talk about audio plug-in technology in general and about different types and formats of plug-ins which are most common today. In the central part I focus on a concrete implementation of one of the most popular audio plug-in technology today, Steinberg's technology called VST – Virtual Studio Technology. I was working on a realization of audio plug-in which generates the delay effect. The implementation takes place through two different methods. First I show the development of plug-ins through the basic developement kit VST SDK v3.0. In second part the development takes place through some programs that enable programming by the method of visual programming
