Originální abstrakt

This paper presents and compares methods of digital audio signals synthesis with band-limited frequency spectrum, i.e. without the aliasing distortion. The methods are compared from the point of view of the real-time parameter changes such as change of duty cycle of rectangular waveform or continuous change of frequency. Furthermore, most effective methods - successive integration of band-limited impulse train and method of differentiated parabolic waveforms, are then compared from the point of view of the aliasing distortion products and computational complexity. These methods were integrated into a VST plug-in that generates an audio signal in real time.
