Overview
The term "CD Quality" is used to describe a digital recording at a sample frequency of 44.1kHz and word length of 16 bits.
History
In the early days of digital audio, there were many different systems manufactured by different companies; and computer technology was advancing rapidly. In order to make a viable product for consumer applications, SONY and Phillips worked together to develop Compact Disc technology or the "CD" in the early 1980's. At the time it was decided that, based on the dynamic range of analog recording systems, the theoretical dynamic range of 96dB made 16 bit resolution acceptable for high fidelity applications. A sample frequency of 44.1kHz was adequate to record audio signals up to 20kHz and worked well with the video systems used to record and edit the digital audio in the process of making the CD master tape.
Basics
As the general public became familiar with digital audio through listening to CD's,
