The tools located under ld-process-ac3 do not seem to follow the standards set by the rest of the tools. Naming conventions are not followed (ld-process-ac3 contains a tool called ld-ac3-demodulate with no care of naming conventions) and standard --help options are completely missing.

Looks like the whole tool was created without any care of matching the code or the UI/UX to any of the existing tools. This is very inconstant and should be fixed.
