Adding a coins ringing sound to the information about it

This might just apply for silver, but I was wondering if it would be a ridiculous idea to allow users to upload audio of a coin ringing to the other info such as weight, size etc.

This could really help with determining whether a coin is real or not, as all coins have a specific ringing sound. I know I for one would be more than happy to upload the sounds of many of my coins ringing

I had a similar idea in the past but then, recording wavelangths of a couple of similar silver coins, discovered they have different “image” with peaks not at the same frequences, so I dropped the idea. 

I'm not sure we really need a functionality to upload audio attachments to user collections.

But on a similar idea, there is a third-party mobile app which relied on the Numista API and checks your coins based on their sound: https://play.google.com/store/apps/details?id=com.cointester.cointester
