This is in contrast with lossless data compression, where data will not be lost via the use of such a procedure.
To play the lossless data you need a compatible mp3HD player with decoder otherwise you would be playing just the lossy data.
In other words, for any (lossless) data compression algorithm, there will be an input data set that does not get smaller when processed by the algorithm.
It was very memory efficient, mainly due to the advanced text lossless data compression routines which could compress texts to about 50%.
Monkey's Audio is an algorithm and file format for lossless audio data compression.
It may be combined with other general lossless data compression techniques such as entropy encoding and dictionary coders to compress the remaining suffixes.
Compression ratios are around 50-60% of original size, which is similar to those for generic lossless data compression.
Third, distribution of lossless audio data became easier as the Internet developed.
Since these lossless data compression steps don't add noise into, or otherwise change the contents (unlike quantization), it is sometimes referred to as noiseless coding.
All lossless data compression methods are transparent, by nature.
