Transparency (data compression)

Kurzbeschreibung des Verlags

In data compression or psychoacoustics, transparency is the ideal result of lossy data compression. If a lossy compressed result is perceptually indistinguishable from the uncompressed input, then the compression can be declared to be transparent. In other words, transparency is the situation where compression artifacts are nonexistent or imperceptible. Transparency, like sound or video quality, is subjective. It depends most on the listener''s familiarity with artifacts, and to a lesser extent, the compression method, bit-rate used, input characteristics, and the listening/viewing conditions & equipment. Despite this, sometimes general consensus is formed for what compression options "should" provide transparent results for most people on most equipment. Due to the subjectivity and the changing nature of compression, recording, and playback technology, such opinions should be considered only as rough estimates rather than established fact.
