On a Property of Short-Time RMS Distribution of Music Genres
タイトル(掲載誌)愛知工業大学研究報告 = Bulletin of Aichi Institute of Technology
一般注記In the last decade, personal music players have become used by an increasing portion of the population, particularly young people. Music signal from such players has been a significant threat to hearing because it can reach very high sound volumes without quality loss. This paper describes music level characteristics with musical genres to discuss signal level variation. To estimate total quiet portion of music signal, short time root-mean-square values within 10ms are calculated every 5ms period from music CD. Frequency distribution curves of the short time rms is well expressed by a beta distribution. An index expressing music quietness is defined by the probability of strms going down below -6dB from its rms value. Some relationships between the -6dB probability and musical genres are indicated. It is concluded that the -6dB probability takes larger value in Classical, HipHop/Rap, Jazz and R&B genres than others.
