Abstract
Based on the analysis of the ITU-R primary documents and the experience gained by the authors, the influence of digital audio data compression algorithms, the type of modulation of subcarrier frequencies in the OFDM block and code rate, as well as the signal-to-noise ratio during radio reception on the quality of the transmitted audio content is considered. Recommendations on the choice of the listed parameters are given.
