This is Audiograph -- The Bay Area's sonic signature.
Each week, we'll play you a sound recorded somewhere in the Bay Area. Your job? Listen to the sound, guess what it is and where we recorded it, and then call us to let us know.
Think you can identify this Audiograph sound of the week? Call 415-264-7106. If you get it right, you might win a KALW t-shirt! And tell us where to record next!
We'll tell you the story behind the sound Thursday, February 11, 2016 during the 5pm broadcast of Crosscurrents, so tune in!
