[LAU] app for simple editing and recording?

[Renato]

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
