From the developer:
APTDecoder is a method of broadcasting cloud pictures from satellites. APTDecoder can create four grayscale and colour enhanced images. Coloured images are created based on an colour lookup table (CLUT). A CLUT editor is also included. It renders the raw image (fully decoded) while recording signals transmmitted from the satellite or while processing an audio file.
