The fade-out sound effect designates a strict decreasing of the volume of an audio signal, starting from the detected initial level down to silence. Audio fade-outs are usually processed in off-line mode that is within audio editors, by employing different transcendental functions to set the time-related evolution of the audio level. However, the proliferation of mobile devices as well as the increasing popularity of web applications, implemented in HTML5/JavaScript, press for computing techniques suitable for real-time processing. In this context, having in view that the computation of the outputs of transcendental functions is very time-consuming, in order to construct the audio fade-out profile, a technique suitable for real-time computing is developed in the present investigation. The suggested techni-que is validated by means of an implementation in pure JavaScript, put forward with the purpose of immediate testing.
