LAME - History

History

The name LAME is a recursive acronym for "LAME Ain't an MP3 Encoder". Around mid-1998, Mike Cheng created LAME 1.0 as a set of modifications against the "8Hz-MP3" encoder source code. After some quality concerns raised by others, he decided to start again from scratch based on the "dist10" MPEG reference software sources. His goal was only to speed up the dist10 sources, and leave its quality untouched. That branch (a patch against the reference sources) became Lame 2.0. The project quickly became a team project. Mike Cheng eventually left leadership and started working on tooLAME (an MP2 encoder).

Mark Taylor then started pursuing increased quality in addition to better speed, and released version 3.0 featuring gpsycho, a new psychoacoustic model he developed.

A few key improvements, in chronological order:

  • May 1999: a new psychoacoustic model (gpsycho) is released along with LAME 3.0.
  • June 1999: The first variable bitrate implementation is released. Soon after this, LAME also became able to target lower sampling frequencies from MPEG-2.
  • November 1999: LAME switches from a GPL license to an LGPL license, which allows using it with closed-source applications.
  • May 2000: the last pieces of the original ISO demonstration code are removed. LAME is not a patch anymore, but a full encoder.
  • December 2003: substantial improvement to default settings, along with improved speed. LAME no longer requires user to use complicated parameters to produce good results.
  • May 2007: default variable bitrate encoding speed is vastly improved.

Famous quotes containing the word history:

    “Spain is an overflow of sombreness ... a strong and threatening tide of history meets you at the frontier.”
    —Wyndham Lewis (1882–1957)

    “Most events recorded in history are more remarkable than important, like eclipses of the sun and moon, by which all are attracted, but whose effects no one takes the trouble to calculate.”
    —Henry David Thoreau (1817–1862)

    “The history is always the same the product is always different and the history interests more than the product. More, that is, more. Yes. But if the product was not different the history which is the same would not be more interesting.”
    —Gertrude Stein (1874–1946)
