Audioboo is an application for recording and sharing your voice with the world. This free version allows you to create audio up to 5 minutes in length and post that to your own account on the web. You can add titles, tags, geolocation info and a photo to the recording before you upload it and we'll save all that with the file. The audio can then be shared with your followers or via Facebook, Twitter & more social networks by managing your account at http://audioboo.fm.
In addition, you can also listen to featured, followed, popular, recent, nearby and favourite boos in the app (as well as your own) and view photo & location details if attached.
You don't need to create an account to start recording but it'll certainly help you keep track of your boos in the future. You can also sign in using Twitter.
Great app, would highly recommend it!
