Music is a quintessential part of the Zelda series. And some of Zelda’s most iconic melodies go all the way back to the original game, on the Nintendo Entertainment System. These tunes were born in an age of 8 bits, and 5 lo-fi channels of audio. But those limitations forced composer Koji Kondo to make them as distilled and powerful as possible.

The history of recorded sound stretches back over a hundred and fifty years, starting with a device that could “record” a voice on a piece of paper. Today, we can enjoy lossless streaming anywhere we go… but getting here wasn’t easy. In this episode, we worked with Qobuz, the high quality music platform, to chart the history of audio mediums, from cylinders made of tin foil and wax, to vinyl, 8-track, cassette, CDs, and mp3s. Along the way, we explore the innovations and quirks of each format, with memories sent in from our listeners and the 20K team. Featuring Adam Tovell from the British Library Sound Archive.

Baseball fan or not, there’s one song that virtually every American knows… or at least, we think we do. “Take Me Out to the Ball Game” is one of the top three most recognizable songs in the country, next to “The Star Spangled Banner'' and “Happy Birthday.” But if you dig into the lyrics, you’ll find a forgotten message buried among the peanuts and Cracker Jack.

Our vocal system is incredibly complex. What we call “the voice” starts with very precise movements of our vocal cords, and then goes through an entire “resonation system” that includes our throat, mouth, lips, tongue, and teeth. With enough control over these components, people can do some truly mind-bending things with their voices, creating sounds that feel out of this world—from rumbling lows to piercing highs, and even two notes sung at once. This episode features vocal coach Matt Ramsey and Tuvan musician and throat singer Albert Kuvezin. Check out our new store at 20k.org/shop. Follow Dallas on Instagram, TikTok and LinkedIn.

Why do bugs make the sounds they do? And how do they make them? In this episode, we explore the un-bee-lievable world of insect sounds, including crickets who craft tools to make themselves louder, and moths who can jam the natural sonar of bats.

In honor of Mental Health Awareness month, we’ve revamped one of the most personal episodes we’ve ever worked on. To create it, Dallas worked with the team from Meditative Story to tell a story from his former life as a musician. It’s about losing the thing that had defined his life for more than a decade, and finding something entirely different in the process. This remix concludes with an all-new segment where Dallas reflects on what it was like to finally share this story. Check out our new store at 20k.org/shop.

 In the 1960s, stereo sound revolutionized the music industry. But it turns out, a pioneering engineer named Alan Blumlein had actually invented stereo a full three decades earlier. Due to tragic events in World War II, his innovations were forgotten for decades. In this episode, we worked with OnePlus to tell the story of how audio has evolved from mono, to stereo, to quadraphonic, to surround sound and beyond. Today, we even have immersive, three-dimensional systems that can simulate 128 speakers using just two.

“Soundalikes,” also called “voice doubles,” are voice actors who perform as characters that were originally played by someone else. They’re used extensively by studios like Disney and Pixar, in order to keep their iconic characters consistent across games, rides, toys, and TV shows. In live action movies, soundalikes fill in for the leads, and record lines for the film’s many rough cuts. But being a great voice double is about much more than just being a good impressionist.
