Audacity 4 is a complete revamp of the ‘world’s most popular’ audio editor

Audacity 4 has been in the works for some time, and had its own mini controversy last year when an unfortunate redesigned logo started making the rounds. The final version of the new icon isn't nearly as bad as the early rendition that was circulating last October.

But more importantly, all the promised improvements to the self-proclaimed "world's most popular audio editing and recording app" are here, turning Audacity from a free and capable but extremely clunky audio editor into a powerful modern tool.
