Is there an easy to use Equalizer for Ubuntu based Distros?

[Linux for blind general discussion]

I can't help with the equalizer, but regarding conf files:

In general, conf files are just plain-text files that can be edited in
whichever text editor you prefer. That said, editing a conf file is a
rather application-specific task, so it's less "learning how to edit
conf files" and more "learning how this particular application formats
its conf files" with some applications having conf files that are
rather human-readable and fairly self-explanatory and others having
conf files that are hard to parse even with a guide.

Though, one thing you could try is looking up the equalizer package
with no configuration tool in a package manager and checking the list
of packages that depend on it. If there exists a frontend that lets
you avoid messing with conf files, it probably depends on the
low-level equalizer. I know the curses-based Aptitude has such
functionality, but I sespect other frontends for apt have it as well.

To look this up in Aptitude:

>From the command line:

sudo aptitude

This will bring up aptitude's main package list, which sorts packages
into a hierarchy by install status, software category, and License.
Press forward slash to bring up a search box.

type the name of the package you want to check what depends on it and
press enter.

If the first result isn't what you're searching for, press n to go to
the next result.

Once you've found the package you're interested in, press enter to
bring up its details.

The details page will have the name and description at the top, tags
and some data about the package(such as size, architecture, source,
and maintainer), and then a list of related packages sorted by
relationship.

The relationships section will start with packages the selected
package depends on, recommends, suggests, etc if there are any,
followed by conflicts and breaks, and each section can be
expanded/collapsed by pressing enter on its heading.

Further down will be a section for packages that depend on the
selected package, and while most relationship section are only
displayed if there are packages in them, this one will be displayed
even if there are zero packages in it. It will have subsections for
depends, recommends, and suggests, and if the selected package has any
aliases, separate sections that call for the alias instead of the
packag directly.

Pressing enter on any package listed in the relationship area will
bring up it's detail page, or a list of versions/alternatives if
multiple versions are available or multiple packages can fulfill the
same dependency.

And for the sake of completeness, the last item of a package's detail
page in aptitude is a list of available versions.

Oh, and lowercase q will take you to the previous screen, capital Q
will prompt exit from aptitude back to the command line, Plus sign
marks the highlighted package for installation, minus sign for
removal, lowercase u refreshes the package list, lowercase g shows you
a preview of what will be done, and pressing g again on the preview
executes changes.
