How to check media content for uniqueness?

Tell me, are there any implemented technologies to determine the uniqueness of media content?
Example, loading only unique mp3 files into the database.
I heard something about contentID - if I understand correctly, it can only be used as part of working with youtube. but I would not like to integrate with it.
Thank you in advance for your help

Get the hash of the file (the hash sum of the file) and save it to the database. If the hash matches when uploading a new file, then such a file already exists.
