But today, WNYC's Audio Search engine allows listeners to find specific audio clips from this public radio station's extensive archives.

All they have to do is enter the keywords for the clip they are seeking — such as "McCain" and "Palin," or "Obama" and "Berlin" — and the WNYC Audio Search engine calls up the clips that most closely correspond to their requests. From there, the clips can be played using the WNYC.org's online player.
