Syracuse University's Belfer Audio Archives has been producing Sound Beat for several years and perhaps you've heard these 90-second segments on your radio station. All of the recordings used are in the Belfer Sound Archive, from speeches to music to the sounds of nature. Each episode give a quick overview or history and a portion of the recording. It's possible to subscribe (free) the Sound Beat recordings and receive the new one each day. You can also add Sound Beat to your web site through a widget.
Sound Beat makes the past available through audio. I can imagine someone wanting to connect these sound bites to other digitized content to make a media rich experience.
