The MP3 Story

In the not-too-distant past we were faced with the challenge of transmitting high-quality audio over phone lines. While this seemed impossible at the time, ideas from psychoacoustics and signal processing and work by many researchers helped the seemingly impossible to become reality: mp3 and other audio codecs enabled the seamless transport of audio over legacy copper phone lines. However, the mp3 story did not end there. The internet was being transformed from a text-based medium into a major carrier for sound of all kinds, including music. This meant changes not only for the payload (from text to audio), but also new dangers for the audio quality delivered to music lovers. And it changed business models for music sales dramatically, shaking the foundations of the music industry. This is the story of MP3.
