LAME Bundles
Packages of LAME, the highest quality MP3 encoder
These bundles contain:- lame.exe - the command line encoder, used from the Windows command shell
- lame_enc.dll - LAME encoding library, generally used with CD rippers, etc
LAME 3.100.1
2020-09-08Bundle compiled with Intel 19 Compiler. win32 compile should work on XP, or later. This a point release with NO changes to the encoding library. The internal mpglib decoding library has been replaced with the libmpg123 decoding library.
LAME 3.100 32bit
2020-04-09Bundle compiled with Intel 19 Compiler. SVN update as of 2020-04-09. Should work on XP, or later.
LAME 3.100 64bit
2020-04-09Bundle compiled with Intel 19 Compiler. SVN update as of 2020-04-09. (For 64bit Windows only.)
LAME 3.100 – Windows ARM64
2025-06-30 Bundle compiled with the MSYS2 environment with Clang(v20.1.3) targeting ARM64, the binaries
are intended to provide native optimized MP3 encoding support on ARM-based Windows devices.
Target Environment:
Platform: Windows 10/11 on ARM64
Compiler: Clang (via MSYS2 - clang-aarch64)
Build System: MSYS2
Installation Instructions:
Download and extract the archive to a preferred location. Add the extracted directory to your
system PATH if desired. Open PowerShell or CMD and run lame --version to confirm that the
archive has been successfully extracted and the executable is functioning as expected.
Limitations from Official Releases:
No known functional limitations relative to the latest version.
Enhancements:
Introduced NEON intrinsics to improve the performance of MP3 Encoding (Thanks to TMKK for hosting
the patches at https://tmkk.undo.jp/lame/index_e.html).
Other supporting patches & build instructions for compiling the LAME MP3 Encoder for Windows-ARM64
and native binaries are included in the bundle provided by MulticoreWare Inc.

2010-09-24A binary which will run on OSX 64 bits (Snow Leopard) compiled by Olivier Petit.
LAME 3.98.2 for MacOS X
2010-05-19A universal binary (lybrary + frontend) which will run on both PowerPC and Intel powered Mac's compiled by Paul Sanders. Works with Audacity
LAME 3995o
2019-06-20halb27s modified lame 3.99.5. It's an extension to Lame 3.99.5 which offers an additional constraint vbr mode option --cvbr x, x from 1 to 10, fractional values allowed, to be used additionally to standard VBR option -Vn. Constrained vbr mode means bitrate is controlled not to go too low. It comes at the cost of an increased average bitrate. This extra cost can be kept very low (down to 0%), while offering remarkable quality improvement for special issues. Incorporates bug-fixed FastCRC patch. Intel 19, 32 and 64 bit compiles.
