Abstract sequence of digital switching signal for switching purposes, apparatus to include such a sequence of switching signal digital information signal in a digital audio and device to receive the information signal provided with the sequence of switching signal.It is a sequence of digital switching signal, and this sequence of switching signal held as a sign of white noise filtered with high pass, previously scanned, of a predetermined length T, with a cut-off frequency is high.That is above the frequency where the intensity threshold characteristic in the silence of human ear has its maximum sensitivity, if possible (Fig. 5). The sequence of switching signal is used for switching purposes (206), for example, to toggle between two information signals (201, 207).
