This is a most excellent place for technology news and articles.
Although not technically free, I would add Reaper to the list for audio editing. It gives you a pop-up asking if you want to buy the program, but it's not required. I know people who have been using it for years without actually purchasing it. (I have since purchased a license because I use it professionally). No features are locked behind the paid license.
