Urban Apps has released an update to Ambiance adding iPad and AirPlay support. Ambiance is an “environment enhancer” application that allows the user to play back a wide variety of ambient noises that can be downloaded from a very large catalog of sounds ranging from nature sounds to sounds from busy train stations. Ambiance 3.1 is now a universal application adding native support for the iPad as well as introducing AirPlay support for full audio streaming to an Apple TV, Airport Express or other AirPlay compatible output device. The new version also fixes a number of issues related to push notifications, caching of pages and general user interface problems. Ambiance is available from the App Store for $3 and is a free update for current users.
