YouTube TestTube : Try AudioSwap and Streams

Want to try out new YouTube features that have not yet gone live on their site? Youtube Testtube lets you try out these new features and give feedback to improve them.

“This is where YouTube engineers and developers test out recipes and concoctions that aren’t quite fully baked and invite you to tell us how they’re coming along. Your comments will help us improve and perfect the mixtures we’re working on. So jump in, play around, and send your feedback directly to the brains behind the scenes.”

Now you can try Youtube AudioSwap, which lets you add music for your video. They have tied up with artists and record labels so that you can add their songs to your YouTube videos. You get a cool soundtrack for your video and the artists get attribution on your video.

Another cool feature is Youtube Streams, where you can create a YouTube room to watch and interact with other users while sharing videos. Everyone in the room can add videos from their Favorites, QuickList, or by pasting in links, and make a running commentary as the videos play.

Using the Testtube requires login to Youtube and then you can check out these tools.
