From Wikipedia, the free encyclopedia

Fraunhofer l3enc was the first public software able to encode pulse-code modulation (PCM) .wav files to the MP3 format. The first public version was released on July 13, 1994.[1] This command-line tool was shareware and limited to 112 kbit/s. It was available for MS-DOS, Linux, Solaris, SunOS, NeXTstep and IRIX.[2] A licence that allowed full use (encoding up to 320 kbit/s) costed 350 Deutsche Mark, or about $250 (US).[citation needed]

Since the release in September 1995 of Fraunhofer WinPlay3, the first real-time MP3 software player, people were able to store and play back MP3 files on PCs. For full playback quality (stereo) one would have needed to meet the minimum requirements of a 486DX4/100 processor.[citation needed]

By the end of 1997 l3enc stopped being developed in favour of its successor MP3enc.[2] Development of MP3enc stopped in late 1998 to favour development of a parallel branch FhG had been developing for some time, called Fastenc.[3] None of these programs are still marketed.[citation needed]
