[LAU] app for simple editing and recording?

hello list, I'd need to: 1) - open mp3/wav files, do some trimming and fade ins/outs and save to mp3/wav 2) - do some recordings of JACK-apps and I'd like to do so in one application. Audacity would be perfect but it doesn't appear in patchage; I can only decide it's input from it's prefs, but I need to have multiple apps that go into it (and the prefs dialog won't let me do it)... All apps I found so far do either 1 and are not JACK-apps (or have a problem similar to audacity's) (Rezound,Sweep) or do 2 but not 1 (Ardour,jack_rec) I haven't tested the following, and would like to know from you if any of them does both 1 and 2 without me testing them all: qtractor,muse,ecasound,rosegarden thanks renato
