cd-quality

The term is a modern compound formed in the late 20th century from the initialism "CD", representing the digital audio storage medium "compact disc", and the English word "quality". "Quality" itself has a long etymological journey, originating from the Latin qualitas, a term coined by Cicero to translate the Greek philosophical concept poiotēs (suchness), derived from qualis (of what kind). The compound "CD-quality" emerged in marketing and technical specifications to denote audio fidelity that matches the clear, low-noise digital reproduction characteristic of the original commercial compact discs, thus applying an ancient concept of inherent attribute to a modern technological benchmark.
