Music lovers seek to pump up digital audio quality

Some experts say new formats are unlikely to take hold because most consumers cannot tell the difference. "I hate to use the term 'snob appeal' but that's really what it is," said Colby Leider, director of music engineer at the University of Miami's Frost School of Music. Leider, who has studied both electrical engineering and music composition, said while it is true much data is lost when music is compressed to the MP3 format, "it works because it removes the portions of sound that most humans can't hear."
