FIELD: communication means.
SUBSTANCE: auxiliary digital audio signal is generated at the input of the first transmission rate converter from the main digital audio signal, note here that said auxiliary digital audio signal corresponds to the main digital audio signal. In these main and auxiliary digital audio signals, identical interference and distortions occur due to similar types of digital processing by change of transmission speed. At that, in the main digital audio signal these noise and distortions occur due to digital processing at successive changes of transmission speed in the communication channel. In the auxiliary digital audio signal, exactly the same noise and distortions occur due to the same processing only at the input of the first transmission rate converter. In this case, all treatments, corresponding to processing in the main digital signal with successive changes in the transmission speed of this signal in the communication channel, are carried out in an auxiliary digital signal only at the input of the first transmission rate converter.
EFFECT: high efficiency of transmitting an audio broadcast signal by reducing distortions and interference when changing sampling frequency and transmission speed.
