Generically, crossfade duration is the period of time during which a Media Player fades out one song while fading in the next song.
For example, if crossfade duration is set to 2s, then the music player will fade out song a during the last 2 seconds of the track, while fading in the first 2 seconds of the next track.
Caveat: I say 'generically' because it's actually a little more complicated than that. When crossfading is enabled, a player will usually fade-out Track A, and fade-in Track b, but the timing for fade-in and fade-out and the slope of the fade-in and fade-out curves may vary, making for slightly different implementations between different media players.
Most multimedia players will make the change from song to song more seemless by fading the next song in ontop; this is crossfading.
Also, some music cd burning programs allow the cd to be burned with a cross-fade between songs.
