Precise Gapless Playback
As opposed to heuristic techniques, what is often meant by precise gapless playback, is that playback timing is guaranteed to be identical to the source. By this definition, a precise gapless player is not allowed to introduce either gaps or overlaps (crossfading) between successive tracks, and is not allowed to use guesswork.
Apart from accounting for playback latency, the preciseness here lies in treating lossless data as-is, and removing the correct amount of padding from lossy data. This is not possible for all file formats.

Famous quotes containing the word precise:
“In contrast to the flux and muddle of life, art is clarity and enduring presence. In the stream of life, few things are perceived clearly because few things stay put. Every mood or emotion is mixed or diluted by contrary and extraneous elements. The clarity of art—the precise evocation of mood in the novel, or of summer twilight in a painting—is like waking to a bright landscape after a long fitful slumber, or the fragrance of chicken soup after a week of head cold.”
—Yi-Fu Tuan (b. 1930)
