There is also Ardour which is FOSS and would be enough for recording as well as Traktion Waveform which has a free and a Pro version, if my memory is correct the difference is what kinds of instruments/effects plugins come bundled with it.
Ardour is the OG for sure! I'm a huge Reaper guy though been using it since 2009. One of the few pieces of software that I truly enjoy using, and the community is great
