LAME source code

SongShrink exports MP3 files with the LAME MP3 encoder. Here is the exact LAME source the app uses, the files and settings it is built with, and how a rebuilt LAME takes the place of the app’s copy.

If you are not a developer

You don’t need anything on this page to use SongShrink. It is here because LAME’s licence asks us to share its source code and the way we build it. Nothing here is SongShrink’s own app code: only LAME’s source and the files that build it.

What LAME is

LAME (“LAME Ain’t an MP3 Encoder”) is a free, open-source MP3 encoder made by The LAME Project. Its website is lame.sourceforge.io.

How SongShrink uses it

SongShrink uses the official, unmodified LAME 4.0 release: the encoder library only, with no decoder and no command-line program. It is a separate library inside the app, so you can replace it:

iPhone, iPad and Mac: LameKit.framework (bundle identifier lamekit.LameKit), a separate dynamic framework.
Android: liblame.so, a separate shared library.

Both are built from the same source. The one file that doesn’t come from LAME is config.h, the build configuration that LAME’s own setup script would otherwise write.

BUILD.md (13.8 KB): how SongShrink builds LAME on iPhone, iPad, Mac and Android, the functions the app calls, how a rebuilt LAME replaces the app’s copy, and what this page doesn’t include (an iPhone or iPad app downloaded from the App Store is encrypted by Apple and can’t be relinked).
config.h, Package.swift and LAME-VERSION.txt: the iPhone, iPad and Mac build files.
CMakeLists.txt: the Android build file.
