SoundCloud, the audio platform, has unveiled SoundCloud Labs, a new site to house experimental projects and features developed in-house, including via its open API. The idea of creating a separate space for cutting-edge development branded as Labs isn't a new one, of course, mostly notably employed by Google. But in SoundCloud's case it perhaps makes even greater sense since the service was originally targeted at music makers but is now aiming to be a much wider consumer play.
