The Recording Industry Association of America (RIAA), in cooperation with the Consumer Electronics Association, DEG: The Digital Entertainment Group, and The Recording Academy Producers & Engineers Wing, formulated the following definition of high-resolution audio in June 2014: "lossless audio capable of reproducing the full spectrum of sound ...
Represents the amount of information, or detail, that is stored per unit of time of a recording. Common examples of bit rates include MP3 which is recorded at 128–320 kbits/s, CD quality audio (LPCM) which is recorded at 1,411.2 kbit/s, SACD (DSD) which is recorded at 5,644.8 kbit/s, and DVD-Audio (MLP), which is recorded at 18,000 kbit/s.

Disc quality: optical disc recorders detect the available speed options based on the data which is available on the disc itself. However, some low-quality discs make a high-speed option available to the software, while the burning process can never reach that speed in practice. The reading and writing process may not happen at a steady speed.
In digital audio, 44,100 Hz (alternately represented as 44.1 kHz) is a common sampling frequency.Analog audio is often recorded by sampling it 44,100 times per second, and then these samples are used to reconstruct the audio signal when playing it back.
The CD+G format takes advantage of the channels R through W. These six bits store the graphics information. CD + Extended Graphics (CD+EG, also known as CD+XG) is an improved variant of the Compact Disc + Graphics (CD+G) format. Like CD+G, CD+EG uses basic CD-ROM features to display text and video information in addition to the music being played.
Compact Disc Digital Audio (CDDA or CD-DA), also known as Digital Audio Compact Disc or simply as Audio CD, is the standard format for audio compact discs. The standard is defined in the Red Book technical specifications , which is why the format is also dubbed "Redbook audio" in some contexts. [ 1 ]
The music publishers are not enthusiastic about this because it permits the production of a CD-quality copy, something they still expect to sell, besides DVD-A. Downconvert the audio to 2 channels, but keep the original sample size and bit rate if the producer sets a flag on the DVD-A disc telling the player to do so.
Connection Bandwidth Dial-up 28.8 to 56 Kbps ISDN 64 to 128 Kbps DSL or Cable 128 to 768 Kbps T-1 1.5 megabits per second (Mbps) T-3 45 Mbps DS-3 45 Mbps These are all decimal usages refering to standard bit rates, and this usage is consistent throughout this document when refering to fixed bit rates, e.g. for standard link protocols.
