10 Years of 20K! How It All Began

To celebrate ten years of Twenty Thousand Hertz, Dallas reveals the oral history of the show, including the career detours, financial gambles, and chance encounters that made it possible. From touring with The Cavaliers, to mixing Mythbusters, to building a sound studio in his basement, he traces the winding path that led him to start a podcast… and the act of generosity from a personal hero that helped it find an audience. Plus, we open the archives to play the unaired 20k pilot that he can barely stand to hear.

He was deaf for 35 years + Listener Stories kickoff

Last year, we ran three full episodes of listener-produced stories. But one beautiful story was just a little too long for the final cut… and we couldn’t leave it behind. In this episode, sound designer Jesse Herrera tells the story of his grandfather, who lived in silence for 35 years before receiving a cochlear implant, and the overwhelming, joyful process of learning to hear again. Afterwards, Dallas and Casey reflect on last year’s Listener Stories and kick off this year’s competition.

Doctor Who & The BBC Radiophonic Workshop

What does a time machine sound like? Or a magic carpet? For the BBC Radiophonic Workshop, that was just another day at the office. For 40 years, this oddball collective of engineers and composers pushed the boundaries of sound design, crafting eerie atmospheres, quirky jingles, and the iconic audio of Doctor Who. In this episode, we explore the rise and fall of this pioneering studio with composer and archivist Mark Ayres, and uncover how these sonic wizards shaped the future of sound.
