I also cannot understand why anyone would recommend Audacity.
I get flak for this, but Audacity is my "proof" that GIMP's name is why people don't use it, not the UI.
Like GIMP, Audacity's UI is awful, but people still use it. :)
as for the UI, i don't get it. what's so bad about it? and how is this one better? i looked at both and ardour too. so far audacity is the only one that has a feature to detect silence and label it. it's pretty easy to use too. i use this to detect chapters and create a chapter index for audio books. last one i did this week took only a few minutes, and most of the time was typing the chapter titles into audacity. i could not figure out how to do this in ardour or audiomass
Far more intuitive, I think. Keyboard shortcuts and cutting and pasting similar to what you'd get in e.g. Word.
