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.

Today, we can enjoy lossless streaming anywhere we go… but getting here wasn’t easy.

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 an...

“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. Featuring Rick Dempse...
