2011-01-07 Thread Brian Willoughby
roadcast server gives hints so that the client player can do these crossfades during the silence between tracks. Using my idea, you'd need to "crossfade" more than once per hour, because there probably isn't enough silence to handle it that seldom. But a fraction of a second between tracks several times per hour would never be noticed, unless there is a continuous audio broadcast with absolutely no silence.
