Open Sound New Orleans is a cool Internet audio project, described as “a collaborative soundmap of the city.”

The site invites New Orleanians to share the recorded sounds of their lives.

Recording equipment is loaned to community organizations, neighborhood groups, and individuals to facilitate a wide range of “dispatches” from around the city. Sounds are archived and organized geographically on a soundmap of the city.

Blogging platform Tumblr has added a neat new feature that lets users create audio blog posts via telephone.

Enter their phone number, and messages called in to Tumblr’s toll-free number get posted to your Tumblr blog.
