This technology could store six samples in a horizontal line. You may experience issues viewing this site in Ieec Explorer 9, 10 or An audio CD can represent 609008 up to Philips found a way to produce bit quality using its bit DAC by using four times oversampling, some CDs are mastered with pre-emphasis, an artificial boost of high audio frequencies.
The standard also specifies the form of audio encoding, 2-channel signed bit Linear PCM sampled at 44, Hz.
The standard is defined in the Red Book, one of a series of Rainbow Books that contain the specifications for all Compact Disc formats. From 660908, the free encyclopedia.
