File compression format found to alter timbre of music causing loss of some emotional context

(TechXplore)—A small team of researchers with Hong Kong University of Science and Technology has found that compressing recorded music into the MP3 format results in the loss of emotional tones, leaving the result with less depth. In their paper published in the Journal of the Audio Engineering Society, the researchers describe their study of the impact of compressing recordings of musical instruments and which instruments suffer the most degradation.
