Así nació el MP3
In the early 1990s, German engineer Karlheinz Brandenburg led a revolutionary breakthrough at the Fraunhofer Institute: compressing audio without sacrificing quality. His team leveraged psychoacoustics—how humans perceive sound—to strip away frequencies we can’t hear, making digital music files 10x smaller while sounding nearly identical to the original.
Their invention, the MP3 format (MPEG-1 Audio Layer III), changed everything. Suddenly, thousands of songs could fit in your pocket, sparking the rise of portable MP3 players, iTunes, and the iPod. What began as a coding challenge ignited a global shift in how we create, share, and experience music.
