Subjective Evaluation of Sound Quality of Musical Recordings Transmitted via the DAB+ System
The results of research on the sound quality of various kinds of music transmitted via Digital Audio Broadcasting using Absolute Category Rating and Comparison Category Rating methods of scaling are presented. The results showed that bit-rate values influence significantly the results. A Spectral Band Replication processing of signals increases the sound quality higher for low bit-rates than for higher values, dependently on a kind of music. The spatial attributes of sound, as a perspective, spaciousness, localization stability and an accuracy of phantom source, also are dependent on the bit-rate, but these relations are different. It was also found that a method of evaluation gives different results, and a CCR method is more accurate for sound assessment for higher bit-rates.
