Learn all about four different types of music storages over time on our blog/website here and on our YouTube video here! The first is analog recording — think of old vinyl records that are slowly coming back in style! The second is the compact disc (CD), which are still commonly used. The third is the MP3 player, revolutionized by big players like the iPod. And the fourth is digital streaming, such as Spotify and Apple Music. We also cover what exactly sound is, how we process sound in our brain, and exactly how it is stored in compressed systems.
