We live in a world absolutely saturated with technologically mediated sound. Whether by recording or amplification or transmission and broadcast, for over 150 years now sound has been captured by technology. This episode looks at how, exactly, that happens, in a casual conversation about how sounds--especially musical sounds--are literally produced, how they are turned into signal and information, and how they are turned back into sound.

It's an enlightening look into processes that we all use, depend upon, and enjoy every day.
