Computers have become important tools of studio work and live performances among both amateur and professional musicians. Musical software are widely used for recording, processing and for live shows as well. A particular type of musical applications are the virtual instruments, which are mainly used during computer aided composing and concerts.
In many cases, virtual instruments synthesise the sound of an existing musical instrument. Instead of using these large, expensive instruments that are often hard to transport, a convenient solution can be to play such virtual instrument that is capable of creating the sound of the original instrument.
Many approach exist for the synthesis of sound. One of them is physical synthesis. T Physically based virtual instruments synthesise sound with the use of modelling the physical processes of sound creation. In theory, this approach leads to the most precise imitation of the sound of the original instrument. Another advantage is that its parameters have physical meaning.
The goal of this thesis was to create a virtual instrument that is founded on a physically based drum model. A striking surface serves as the controller of the model, the user plays on this device. My goal was to develop a versatile instrument with rich parameters that is capable of creating diverse drum sounds.
In the introduction of this work a short summary of the physics of sound creation in drums is presented then an overview of sound synthesis methods is given. In later chapters the drum model is proposed first, then the description of the algorithms used for its controlling follows. In the closing chapter the VST implementation of the model is presented.
