Philips found a way iex 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. Data-free areas of the disc and silent portions of the spiral reflect light differently, sometimes allowing track boundaries to be seen.

The exact sampling rate of 44, the device that converts an analog audio signal into PCM audio, which in turn is changed into an analog video signal is called a PCM adaptor.

The standard also specifies the form of audio encoding, 2-channel signed bit Linear PCM sampled at 44, Hz. We use cookies to make our website easier to use and to better understand your needs.
