So, I make Minecraft short films and wanted to use the original WhatsApp sounds when someone recorded a voice message, so what comes when you recorded a voice message. Can I do that or are they protected by copyright?
It may very well be that they are protected by copyright. If I were you, I would look for sounds that you can use freely, for example those that are under a Creative Commons license.
Ok then I'll do my own chatapp for the short film with my own sounds.
Have fun and good luck!
