I use Audition. I still call it Cool Edit because that's what it is. And I do not pay any subscription to Adobe.
And no, Audition wasn't always subscription based. But to upgrade from CE2K to Audition (when they bought out Syntrillium), they wanted Adobe type price and I didn't go for it. I kept using CE2k until Adobe gave out a free "perpetual licenses " for registered users of CE2K (right before going to subscription). BTW, that upgraded CE2K to 64bits!!
So, my wave editor of choice is Audition.
