Thus, one can consider data compression as data differencing with empty source data, the compressed file corresponding to a difference from nothing.

If after file compression, a user wishes to access a compressed file, the access times may be increased and vary from system to system.

While this method results in gapless playback within consecutive tracks, it can be unwieldy because of the possibly large size of the resulting compressed file.

With some compression formats, images that are less complex may result in smaller compressed file sizes.

The higher the bit rate, the larger the compressed file will be, and, generally, the closer it will sound to the original file.
