digital audio
(foldoc) | digital audio
A sequence of discrete samples taken
from a continuous sound (audio) waveform. Tens of thousands
of samples are taken each second. Each sample represents the
intensity of the sound pressure wave at that instant. Apart
from the sampling frequency, the other parameter is the
digital encoding of each sample including the number of bits
used. The encoding may be linear, logarithmic or mu-law.
Digital audio is typically created by taking 16-bit samples
over a spectrum of 44.1 thousand cycles per second (kHz), this
means that CD quality sound requires 1.4 million bits of data
per second. Digital telephone systems use lower sample rates.
Filename extension: .au (Unix), .snd (MS-DOS, {MS
Windows}).

digital audio tape
(foldoc) | Digital Audio Tape
(DAT) A format for storing music on magnetic
tape, developed in the mid-1980s by Sony and Philips. As
digital music was popularized by compact discs, the need for
a digital recording format for the consumer existed. The
problem is that digital music contains over 5 megabytes of
data per minute before error correction and supplementary
information. Before DAT, the only way to record digitally was
to use a video or a reel-to-reel recorder.
DAT uses a rotary-head (or "helical scan") format, where the
read/write head spins diagonally across the tape like a video
cassette recorder. Thus the proper name is "R-DAT", where "R"
for rotary distinguishes it from "S-DAT", a stationary design
that did not make it out of the laboratories. Studio
reel-to-reel decks are able to use stationary heads because
they can have wider tape and faster tape speeds, but for the
desired small medium of DAT the rotary-head compromise was
made despite the potential problems with more moving parts.
Most DAT recorders appear to be a cross between a typical
analog cassette deck and a compact disc player. In addition
to the music, one can record subcode information such as the
number of the track (so one can jump between songs in a
certain order) or absolute time (counted from the beginning of
the tape). The tape speed is much faster than a regular deck
(one can rewind 30 minutes of music in 10-25 seconds), though
not quite as fast as a compact disc player. DAT decks have
both analog and digital inputs and outputs.
DAT tapes have only one recordable side and can be as long 120
minutes.
DAT defines the following recording modes with the following
performance specifications...
2 channel 48KHz Sample rate, 16-bit linear encoding
120 min max.
Frequency Response 2-22KHz (+-0.5dB)
SN = 93 dB DR = 93 dB
2 channel 44.1Khz Sample rate, 16-bit linear encoding
120 min max
Frequency Response 2-22KHz (+-0.5dB)
SN = 93 dB DR = 93 dB
2 channel 32KHz Sample Rate, 12-bit non-linear encoding
240 min max
Frequency Response 2-14.5KHz (+-0.5dB)
SN = 92 dB DR = 92 dB
4 channel 32KHz (not supported by any deck)
DAT is also used for recording computer data. Most computer
DAT recorders use DDS format which is the same as audio DAT
but they usually have completely different connectors and it
is not always possible to read tapes from one system on the
other. Computer tapes can be used in audio machines but are
usually more expensive. You can record for two minutes on
each metre of tape.

lossless audio compression
(foldoc) | lossless audio compression
Any kind of audio compression in which
the original signal and the decoded signal are bitwise
identical. Lossless audio compression algorithms are usually
based on a data compression algorithm like PKzip or gzip
but specialized for PCM audio data. The signal is divided
into predictable tonal components and unpredictable noisy
components. Tonal components are stored as coefficients of a
predictor, the remaining signal is coded by Rice coding,
Huffman coding or arithmetic coding.

(LPAC) A lossless audio compression

a Winamp plug-in.

mpeg-1 audio layer 3
(foldoc) | MPEG-1 audio layer 3
MP3
MPEG-1 layer 3
(MP3) A digital audio {compression
algorithm} that acheives a compression factor of about twelve
while preserving sound quality. It does this by optimising
the compression according to the range of sound that people
can actually hear. MP3 is currently (July 1999) the most
powerful algorithm in a series of audio encoding standards
developed under the sponsorship of the {Moving Picture Experts
Group} (MPEG) and formalised by the International Organization
for Standardization (ISO).
MP3 is very different from Layer 2, using an additional MDCT
layer to increase frequency resolution. Its scale factor
groups are more optimised for the human ear, and it uses
nonlinear sample quantisation and Huffman coding.
MP3 files (filename extension ".mp3") can be downloaded from
many websites and can be played using software available for
most operating systems (also downloadable), e.g. Winamp for
PC, MacAmp for Macintosh, and mpeg123 for Unix.
MP3 files are usually downloaded completely before playing but
streaming MP3 is also possible. A program called a "ripper"
can be used to copy a selection from a music CD onto your
hard disk and another program called an encoder can convert
it to an MP3 file.

realaudio
(foldoc) | RealAudio
A program from Real Media for playing
audio over the Internet, and the lossy audio compression
format it uses.
The system is implemented as a client/server architecture.
The RealAudio server incorporates an encoder which
compresses sound into RealAudio files. The client side is a
web browser plug-in or add-on (a recent version of
Internet Explorer apparently has built-in support for
RealAudio) which allows the stream of data sent from the
server to be uncompressed and output using the normal sound
facilities of the computer, such as a sound card.
A 14.4 KBps or better modem is required, and a 28.8 KBps
connection is recommended for music-quality sound.

transparent audio coding
(foldoc) | transparent audio coding
A lossy audio compression algorithm
is transparent if the original and decoded signal are
indistinguishable to the human ear. The bit rate depends on
the codec and the audio material. Some codecs (e.g. AAC,
MP3) are optimized for transparent coding at a low data
rate, others (e.g. VQF, MP3Pro, AAC+SBR, WMA) for
distinguisable but pleasant reproduction at lower bit rates.
Typical data rates in kbps for different codecs are:
MP1 288-320
MP2 224-256
MP3 160-224
MPEG-2 AAC 128-160
MPEG-4 AAC 112-144
MPEGplus 160-200
