Looking for Open Source Professional video and sound editing software. [View all]

Let me first explain what my needs are. I'm looking to do radio broadcasting, music/editing and occasionally video as well. For sound, I want up to 24/192 support as well as being able to handle 5.1 as I have a mic that is capable of recording that and I would like to take advantage. Additionally, regarding video, I'm hoping to see support for up to 4K full color video. As it stands full color 1080p will do as I'm looking at bagging a film camera at that level.
Is there any Open Source software I can find that will support that or even more current software that I can actually own, both in software tangibly(discs/download) and my work(I've heard Adobe's current CC agreement gives them the right to use/steal your work)?
Any help would very much be appreciated.
