ABC/HR for Java is a tool for comparing multiple audio samples. It was designed after ABC/HR by ff123 (ff123.net/abchr/abchr.html), so all credits for the idea and the concept go to ff123.

To run the application:

On Windows: (double)click the file abchr.jar in Windows Explorer
On other platforms: type "java -jar abchr.jar" in the command prompt

The program was compiled for JRE 1.4.2 but it might run on older versions. However, since Sun tweaked their reference implementation quite a bit in recent versions I recommend installing the current JRE if you run into any problems. In any case your Java Runtime has to support the Java Sound API 1.0 (Sun's reference runtimes for Windows and Linux support this). It might run on different implementations of the Java Sound API than that from Sun, but since many features of this API are implementation-dependent and I had no opportunity to test different implementations, the program would probably need some tweaks before running properly.
