(gcide) | Lossless \Loss"less\, a.
Free from loss. [Obs.] --Milton.
[1913 Webster] |
lossless
(wn) | lossless
adj 1: characterized by or causing no dissipation of energy
[ant: lossy] |
lossless
(foldoc) | lossless
A term describing a data
compression algorithm which retains all the information in
the data, allowing it to be recovered perfectly by
decompression.
Unix compress and GNU gzip perform lossless
compression.
Opposite: lossy.

lossless compression
(gcide) | Compression \Com*pres"sion\, n. [L. compressio: cf. F.
compression.]
1. The act of compressing, or state of being compressed.
"Compression of thought." --Johnson.
[1913 Webster]
2. (Computers) reduction of the space required for storage
(of binary data) by an algorithm which converts the data
to a smaller number of bits while preserving the
information content. The act of compressing [3].
Note: Compression may be lossless compression, in which all
of the information in the original data is preserved,
and the original data may be recovered in form
identical to its original form; or lossy compression,
in which some of the information in the original data
is lost, and decompression results in a data form
slightly different from the original. {Lossy
compression} is used, for example, to compress audio or
video recordings, and sometimes images, where the
slight differences in the original data and the data
recovered after lossy compression may be
imperceptable to the human eye or ear. The JPEG
format is produced by a lossy compression algorithm.

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.

lossless predictive audio compression
(foldoc) | Lossless Predictive Audio Compression
(LPAC) A lossless audio compression
algorithm with compression ratios from 1.5 to 4, depending
on the input. Software is available for Microsoft Windows,
Linux and Solaris. LPAC files (*.pac) can be played with
a Winamp plug-in.
