INFLUENCE OF PARAMETERS OF VOLUME SIGNALS ON CHANGE POPULARITY OF RADIO PROGRAMS

The criterion of "preferability" of sound is becoming increasingly popular in the creation of algorithms for audio processing and compact representation of the sound broadcasting signal, since ultimately the signal is assessed by the listener and this subjective assessment determines the popularity of the program as a whole. Along with such subjective assessments, it is necessary to study the results of objective measurements of a number of parameters of the sound broadcasting signal, which largely determine the popularity of broadcasting programs. Groups of such parameters that are characteristic of the most popular radio broadcasting stations have been determined: energy, spectral, cepstral and parameters of the shape of the analytical envelope of the signal. The obtained objective and subjective assessments of the statistical properties of radio programs preferred by listeners can be used as guidelines when processing the signal by sound engineers in studios and when selecting control parameters for audio processors.
