Yes GStreamer would be a good base for it. But to be true the filters you are
looking for are mostly missing. What GStreamer can provide today is reording,
level-meters to optimize the gain, some post processing (eq, compression),
encoding and tagging.
Noisefiltering and pop/crack filtering is unfortunately no that easy (define
what a crack is and I'll remove it). I once wrote a noise filter and I have the
c-sources for it. So that could be turned into a gstreamer plugin one day.

On the audio side gnome-media has a sound-recoder for a start. The eq-plugin has
a nice demo.
