Audio editing is still shit. GarageBsnd is on Mac, Audacity has a stupid interface, Cakewalk is the first time I hear that name. On Linux, video editing tools are probably the only way to edit audio, and it's obviously lacking.
Cakewalk has been around for decades. It was a popular paid daw in the late 90s and 2000s. It became free a few years ago. Haven't used it lately. But, used it a lot many years ago. It was a top daw back in its day. I hear it's still pretty good.
Agreed, I've had to mix an entire live show recently and Ardour + a few open source VSTs did the job wonderfully. Took me maybe an hour to get my bearings but it is very well done.
