• A reduction in size or volume.
  • The encoding of data or information so that it occupies less space and/or bandwidth. There are many algorithms used for compression, and depending on the information being encoded, space savings can range from under 10% to over 99%. Compression can also be achieved by increasing packing density. Also called compaction, data compression, or information compression.
  • The variation in the gain of a signal, so that the lower magnitude levels have a higher effective gain than the higher magnitude levels. This results in a more balanced output, where lower-level signals have a better signal-to-noise ratio, while higher levels signal do not overload.
