There's no need to use AA for editing.
Many DAWs, when a wav is double-clicked, open an editing window. Reaper doesn't, and this disturbed me for a while.
However, you don't need a separate editing window. In Reaper, you can zoom in on the wav and do whatever you want within the main window. Once you get used to it, it works extremely well.
Importantly, Reaper allows highly non-destructive editing . . . you can always get back to where you started off. With Logic (which I used before Reaper), if I performed an edit in the edit window, it was there for good.
