@Lauren I would like to post mirrors of the shared file.
You have only said that these it is “Free”, which only implies that anybody can have a copy by no fee, for personal use only, and a backup copy where law allows.
This, like any other work, is by default under copyright. You are giving copies for free, but you are not giving rights over the work. So, “Free” doesn’t imply that we can play them in public, mix them, stream them, broadcast them, use them in other works, package them with other works, create derivative works, sell them, use them without attributing them to you, or any other use case, with the obvious exclusion of fair use when appropriate.
I would like to post mirrors of the shared file. I’m required by law to ask for permission to do that. I would prefer if you could – please – give an explicit license, that way anybody would be able to know (without asking you) what rights are you conceding to the public, or if you are releasing the shared file with all rights reserved. Consider also that people may just assume they can do whatever with the shared file - which is probably true, but it is not up to me to tell - and also that being explicit regarding the license won’t hurt.
You may choose any license you want. Yet, I would like to suggest to [choose a license from Creative Commons] (https://creativecommons.org/choose/).
In case of doubt, when I say “the shared file” I mean the file - or any copy of the file - with name “RJFS+Contact+Mic+Twitch+Stream+SFX.zip” with size of 188589700 bytes and SHA-256 “9930BD413954D3FA5347C98119D75B58C4F4B4F07B0454A730EED0FB13867DB0” that is currently - at the time of writing - avilable on the url you provided.
