"Preserve every ounce of tonality"

"As more listeners turn to music downloads and the compact disc seems headed for history's scrap heap, a growing number of artists are making a renewed effort for better-sounding tracks, online and on disc.

It's generally accepted that regular MP3 music files compromise CD sound quality for convenience and portability. (Some listeners argue that even CDs are less than optimal.)"

"High-Frequency Harmonics"

"A line of headphones from Colorado company Able Planet increases the clarity of high-frequency audio without increasing its volume. The technology is aimed not only at the elderly, but also at younger people who hope to avoid hearing damage and at video gamers who want to hear each other over the din of virtual battlefields."
