    Since the early days of the CD, some people realized there was a more efficient way to deliver music.

    When the very first CDs started appearing on the shelves of music stores, people who were familiar with data storage already knew these discs were an inefficient delivery system. This was especially true for those who studied psychoacoustics, the science of sound perception.

    As early as the 1980s, one German team working with empirical psychoacoustic data started experimenting with digital music compression.

    In 1987, a team lead by doctoral student Karlheinz Brandenburg came together at the Fraunhofer Institute in Germany. Their goal was to reduce the size of digital audio files by way of extracting bits of information and sound that were scientifically proven to be imperceptible to the human ear.

    Originally, the goal was to reduce the size of a CD track, which averaged about 1.4 million bits, to one-twelfth of its size, i.e., about 128,000 bits.

    After years of testing and collaborating, the team finally reached their goal. They took music from every genre and used the recordings of a single human voice, bird sounds and even jet engines in order to perfect their compression methods. Interestingly, the human voice on its own proved to be the most challenging sound to deal with. Fun fact: the team tested it by using the acapella intro to Suzanne Vega’s Tom’s Diner.

    The group continued perfecting their work and it wasn’t until 1989, when Brandenburg collaborated with James Johnston, who was working independently on his own psychoacoustic algorithm at AT&T-Bell Labs, that the quality of their compressed files started to sound indistinguishable from that of a CD.

    Great app. Good selection of book summaries you can read or listen to while commuting. Instead of scrolling through your social media news feed, this is a much better way to spend your spare time in my opinion.
