Terminology
Dolby Digital
Dolby Digital is a digital audio compression technology
developed by Dolby Laboratories that allows large quantities of
audio data to be efficiently recorded on discs. It is compatible
with audio signals from mono (1 channel) all the way up to 5.1-
channel surround sound. The signals for the different channels
are completely independent, and since the sound is high quality
digital there is no loss of sound quality.

original recording without adding any sounds to or changing the
sound of the source.

Linear PCM audio (LPCM)
LPCM is a signal recording format used for music CDs.
Whereas music CDs are recorded at 44.1 kHz/16 bits, DVDs are
recorded at 48 kHz/16 bits to 96 kHz/24 bits, thereby achieving
higher sound quality than music CDs.
