There are lots of non-FOSS but effectively-free alternatives. Ocenaudio is way better than Audacity in gobs of ways, except it's not multi-track. Reaper is pretty great but if you're hoping for commercial use with $20K+ gross/year, you need to pay $200+ USD.
In FOSS land, Zrhythm, Qtractor, LMMS...but these are DAWs so again it depends on what you were using Audacity for. You could even learn sox and maybe benefit from some command line use, like writing scripts for things you need to do all the time.
My advice: List the specific tasks you need to do, and aim to find 2-3 apps that will fill the gap. Then any extras on top of that will be gravy.
Edit: Oh and you can also use FOSS like Blender and render edited sound to mp3, or KDEnlive, or other software that's video or animation related. So if you already know those tools, or like how they work (in some ways they are pretty slick!) then they may fit better than other audio-only software.
