audio/x-aac vs. audio/aac

[drone1]

Hello.

I see audio/x-aac is supported in this library, but I don't see audio/aacwhich I believe is the widely accepted form, registered with the Internet Assigned Numbers Authority (IANA).

I'm not an expert on the subject, so I'm just curious if I should be using x-aac instead, or if perhaps there should be support in mime-types for the more modern version?

Thank you.

audio/x-aac is deprecated, since that mime type comes from the Apache list. Maybe once we update mime-db, audio/aac will be the supported one, and audio/x-aac will no longer be available (this is just a guess, we would need to check once the automation in mime-db is fixed (jshttp/mime-db#345)), although such a change would probably be semver-major for this package.
