CUSTOMIZING AUDIO FADES WITH A VIEW TO REAL-TIME PROCESSING

Abstract

To a large extent, an audio fade is distinctly acknowledged as a strict increase (fade-up) or decrease (fade-down) of the volume of an audio content. In this broad context, the widely used fade-in and fade-out sound effects, applied to receive smooth transitions from and down to silence, respectively, appear to be restrictive. Taking into account the increasing demand for multimedia techniques adapted for real-time computing, the present inves-tigation advances straightforward procedures intended for customizing the audio fade-up and fade-down profiles, having at hand well-proven tech-niques of shaping the fade-in and fade-out audio effects, suitable for fast computing.
