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 5.1channel 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. Dolby Pro Logic II Dolby Pro Logic II provides multichannel surround sound from any 2 channel source. It reproduces extended bandwidth playback with 5.1 channels. This is made possible by an advanced matrix surround decoder. This new decoder is able to draw out spatial characteristics of the recording without adding tonal coloration or artificial delays that did not exist in the original. Linear PCM audio LPCM is a signal recording format used for music COs. Whereas music COs 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 COs.
