Suddenly it was readily possible for anyone to create their own MP3 files. ![]() In 1997, an Australian student purchased MP3 encoding software with a stolen credit card, before quickly sharing it on an FTP server online. While this initially seemed feasible, things quickly fell apart, thanks to the very Internet that Fraunhofer had pinned their fortunes on. Teenagers of the time like yours truly loved it, because it looked like a cool vintage stereo. Winamp was one of the most popular audio players of the MP3 era. To drive acceptance of the standard, the decoders used to play the MP3 files would be cheap or free, encouraging consumer uptake. These would be sold at a high price to companies that wished to create software or hardware capable of encoding MP3 files. The original business plan was to monetise the technology through sales of encoders. MusicMatch are notable for having actually paid Fraunhofer for their MP3 license. No Business Model Survives First Contact With The Enemy MusicMatch Jukebox was a popular CD ripper and MP3 player. In a fateful email on July 14, 1995, the team decided that their files should bear the now-famous. With its small file size and high quality, it was perfect for sharing over the slow connections of the time period. With the development of the Internet happening at a rapid pace, the Fraunhofer team realised their standard had the possibility of becoming a defacto standard for audio on the platform. The final results were published in the MPEG 1 standard in 1993. The aim was to create the Layer III codec that could deliver the same quality at 128 kbps as Layer II could at 192 kbps. A team of researchers at the Fraunhofer Institute took the psycoacoustic coding filter bank techniques, while mixing in some ideas gleaned from the competing ASPEC proposal to MPEG. The MUSICAM technology became the basis for much of the original MPEG 1 Audio Layers I and II. By eliminating data corresponding to these sounds that aren’t perceived anyway, it became possible to store more audio in less space without any perceived effect for the listener. This takes advantage of the effect of auditory masking, a perceptual limitation of human hearing where some sounds mask others from being heard at the same time. One of the main techniques to come out of the process was MUSICAM, which adopted a psychoacoustic model of human hearing to aid compression. Desktop computers at the time with clock speeds under 100MHz would struggle to play CD-quality files. Around the time the MP3’s name was decided upon, the Pentium was cutting-edge technology. ![]() Four working groups were created, which began to work further on a variety of encoding methods. The next year, 14 proposals were submitted. Things began to pick up steam when, in 1988, the Moving Picture Experts Group called out for an audio encoding standard. In the 1980s, researchers around the world were working on various encoding methods to solve this problem. In an era where hard drives were measured in tens or hundreds of megabytes, storing uncompressed digital audio at CD quality - around 10MB per minute - wasn’t practical. ![]() Finding a method of compression that didn’t compromise audio quality was key. The aim was to create a codec capable of encoding high-quality audio at low bitrates. The least expensive option rings in at $0.22 per megabyte, which means your 700 MB audio CD would cost $154 to store without compression (10x the cost of buying an album at the time). Twenty-five years on from the date the famous “.mp3” filename was chosen, we take a look back at how it came to be, and why it took over the world.Īudio Big, Disks Small 1995 hard drive prices from an LA Trade ad in BYTE Magazine. The subject of bitter raps and groundbreaking lawsuits, this development from Germany transformed the music industry as we know it. However, the online audio revolution really kicked off with the development of one very special format. In the streaming era, music is accessed from a variety of online services, ephemeral in nature and never living on board the device.
