Do you need a few suggestions on how to spend your time in the Bay Area this weekend? Well, we’ve picked out a few special events just for you.

All week long we've been playing this sound, and asking you to guess what exactly it is and where exactly in the Bay Area we recorded it.

This auditory guessing game is part of Audiograph, a crowd-sourced collaborative radio project mapping the sonic signature of each of the Bay Area’s nine counties. By using the sounds of voices, nature, industry, and music, Audiograph tells the story of where you live, and the people who live there with you. Every Thursday, we reveal the origins of that week's sound on Crosscurrents, and here in weekly blog posts.
