Official libmp3lame Source Code Repository

This article provides the exact location of the official source code repository for libmp3lame (LAME), the industry-standard open-source MP3 encoding library. It details the primary hosting platform, the version control system used by the developers, and how to access the official codebase.

The official source code repository for libmp3lame is currently hosted on SourceForge.

Although many developers look for modern open-source projects on GitHub or GitLab, the LAME development team continues to maintain their upstream, authoritative repository on SourceForge using Subversion (SVN) rather than Git.

Official Repository Details

• Project Homepage: https://lame.sourceforge.io/
• SourceForge Project Page: https://sourceforge.net/projects/lame/
• Web-Based Code Browser: https://sourceforge.net/p/lame/svn/HEAD/tree/trunk/lame/

How to Check Out the Source Code

To download the latest development version of the source code directly from the official repository, you can use the following SVN checkout command in your terminal:

svn checkout https://svn.code.sf.net/p/lame/svn/trunk/lame lame

Unofficial Git Mirrors

Because SourceForge and SVN are less commonly used in modern workflows, numerous read-only mirrors of the libmp3lame repository exist on GitHub. While these mirrors are convenient for integration into Git-based build systems, any official bug reports, patches, or updates must still be directed to the main SourceForge portal to reach the active maintainers.
