The files in this directory contain the code of the ALUT library. They typically compile to make 'libalut.so' on *nix platforms or to 'alut.dll' for Windows platforms. There is also a header file 'alut.h' in ../include/AL which gets installed into $(includedir)/AL/alut.h on *nix platforms and someplace else entirely on Windows platforms. The file 'helloworld.wav' is the original voice recording of Steve Baker saying this immortal phrase. It is converted into a large hexadecimal data block inside alutWaveform.c - but this file is retained in version control just in case anyone ever feels like re-doing it. The format is 16bit PCM, 1 channel, 44.1kHz sample rate.
