LAME is, probably, the best MP3 encoder ever developed (LAME has a decoder too). LAME binaries have two parts :

1. A statically linked command line: "lame.exe" on Windows, "lame" on Unixes.

2. A dynamic link library/shared object: lame_enc.dll on Windows, libmp3lame.so on Linux and libmp3lame.dylib on Mac OS X exporting a standard API .


LAMEOnJ is a 100% Java API wrapping the standard LAME API. LAMEOnJ Java methods call the exported lame_enc.dll (Windows),libmp3lame.so (Linux), libmp3lame.dylib (Mac OS X) methods and LAME native structures are reflected as symmetric Java classes.

Under the hood LAMEOnJ uses JNIEasy , the Java Native Objects bridge, between Java and C/C++.


LAMEOnJ has two levels or versions:

1. A C symmetric API: Java classes and methods mimic the LAME structures and methods. The programming style is almost the same as the C style.

2. An Object Oriented API: Java classes and interfaces encapsulating the boring tasks related to C programming in a simpler and robust API, and providing easy methods to encoding WAV files or WAV/LPCM streams.

LAMEOnJ wraps the BladeEnc API too (C and OOP version), this API is only provided by the Windows version of LAME (lame_enc.dll).

LAMEOnJ is licensed under LGPL and is a SourceForge project.

What do you think about bringing to Java the enormous legacy of the C/C++/native world?
