The Effects of MP3 Compression on PerceivedEmotional Characteristics in Musical Instruments
"Musical instrument sounds have distinct timbral and emotional characteristics, and whenaudio processes are applied to them their timbral and emotional characteristics are changed.This paper investigates the effects of MP3 compression on the emotional characteristics ofeight sustained instrument sounds using a listening test. We compared the compressed soundspairwise over ten emotional categories at several bit rates. The results showed that MP3compression strengthened neutral and negative emotional characteristics such as Mysterious,Shy, Scary, and Sad; and weakened positive emotional characteristics such as Happy, Heroic,Romantic, Comic, and Calm. Interestingly, Angry was relatively unaffected by MP3 com-pression. Probably, the background “growl” artifacts added by MP3 compression decreasedpositive emotional characteristics and increased negative characteristics such as Mysteriousand Scary. For instruments, MP3 compression effected some instruments more and others less.The trumpet was the most effected and the horn by far the least".
