"Ringing" of forged components to discern whether they are cracked or not is a TOTAL WASTE OF TIME.
Most cracks that you would be able to hear would be easily bad enough to see. Those that are there but invisible to the naked eye would be impossible to hear.
The way to see if a crank is cracked or not is to crack test it. This can be done either by a professional or using a proprietary 3 stage crack testing kit for the princely sum of under a tenner.
