Spotify has announced a couple of new features for the next version of its desktop client: gapless playback and crossfade. “Gapless playback lets the tracks flow seamlessly, one to the next, without any silence between. Perfect for classical music, live recordings and concept albums,” notes Spotify’s blog post, saying that gapless will be on by default, although users can turn it off in their preferences. Meanwhile, crossfade is more about fading songs out as the next one starts, DJ-style, although this will be set to off as a default. For now, these new features are desktop-only, although Spotify’s spokesperson tells Evolver.fm to “watch this space” for their addition to its mobile apps too. Talking of crossfading… A newly-revealed patent filing from Apple reveals its work on a beat-matching crossfade technology for Macs and iOS devices. Sound a potential-lawsuit klaxon at this point, if you like.
