I spend a lot of time doing this too -- cutting up band rehearsal tapes into songs and exporting all. As weird as Audacity's UI is, I haven't found anything better than it at this.
i spent about 15 minutes trying to figure out the above. in audacity the whole book was done in 5 minutes.
also, i really don't get what is supposed to be better about that interface. both apps have text menus with lots of functions, and you have to know what the functions do by their name. that makes ocenaudio no easier than audacity in my opinion. and it's not even FOSS.
