Welcome to Audiograph – the Bay Area’s sonic signature. Each week, we play you a sound recorded somewhere in the Bay Area, ask you to tell us what it is, and where we recorded it. We reveal the story behind our mystery sounds every Thursday on Crosscurrents.
This week, it’s our birthday! And to celebrate two years on the air, we’re doing something a little different – a special half-hour birthday edition of Audiograph that brings together some of our favorite sounds and stories from the past year.
