LAME is a high quality MPEG Audio Layer III (MP3) encoder licensed under the LGPL.

LAME is considered the best MP3 encoder at mid-high bitrates and at VBR, mostly thanks to the dedicated work of its developers and the open source licensing model that allowed the project to tap into engineering resources from all around the world. Both quality and speed improvements are still happening, probably making LAME the only MP3 encoder still being actively developed.


  • Quality better than all other encoders at most bitrates.
  • Fast! Encodes faster than real time on a PII 266 at highest quality mode.
  • Many improvements in quality in speed over ISO reference software.
  • MPEG1, MPEG2 and MPEG2.5 layer III encoding.
  • CBR (constant bitrate) and two types of variable bitrate, VBR and ABR.
  • Encoding engine can be compiled as a shared library (Linux/UNIX), DLL , Directshow filter or ACM codec (Windows).
  • Free format encoding and decoding.
  • GPSYCHO: a GPL'd psycho acoustic and noise shaping model.
  • Powerful and easy to use presets.
  • MP3x: a GTK/X-Window MP3 frame analyzer for both .mp3 and unencoded audio files.

To install LAME, run the following command from the command line or from PowerShell:

C:\> choco install lame

To upgrade LAME, run the following command from the command line or from PowerShell:

  • legal\LICENSE.txt Show
    Can I use LAME in my commercial program?  
    Yes, you can, under the restrictions of the LGPL (see COPYING
    in this folder). The easiest way to do this is to:
    1. Link to LAME as separate library (libmp3lame.a on unix or 
       lame_enc.dll or libmp3lame.dll on windows)
    2. Fully acknowledge that you are using LAME, and give a link
       to our web site,
    3. If you make modifications to LAME, you *must* release these
       modifications back to the LAME project, under the LGPL.
