Maximum Compression's goal is to show the maximum achievable data compression ratio for several filetypes (text, executable, jpeg etc).
PAQ8M is identical to PAQ8L in compression for non JPEG data, it takes #1 place on the SFC benchmark (method 2) and widens the gap to #2 (WinRK).
THOR 0.3a and QazaR both have better compression while THOR, written in Delphi(!), is also faster then previous version; it now clocks a compression speed of almost 43 MB/s in MFC test.
Compression is used during sound recording, live sound reinforcement, and broadcasting to improve the perceived quality of audio.
Compression is used extensively in broadcasting to boost the perceived volume of the sound track while keeping it within strict limits (broadcasters in most countries have legal limits on instantaneous peak volume they may broadcast).
Compression is also often used in music production to make performances more consistent in dynamic range so that they "sit" in the mix of other instruments better and maintain consistent attention from the listener.
