I currently use Audacity as my audio editor, it's very powerful with what it does. However, it does not have a real time spectrum analyser, and it does not have a real time graphic equaliser. Both would be really helpful in cleaning up old / damaged audio to make it more listenable.
Is there a lightweight / easy to use Linux package that can do this and still work like Audacity?
It must be able to use Pulse / ALSA (don't want to have to install yet more stuff like Jack and configure it).
