I've done quite a lot of attempts of audio restoration but I'm not
particularly good at it. It's not easy.

When you work on audio files I believe it helps to keep a basic fact of
the trade in the back of your head: Tweaking audio is *always* a
question of *subtracting* from the source. You can never add anything
that's not already there. That is technically impossible.

To illustrate with a very basic example; If you got a recording that has
no bass, there will never be any bass on that recording. The bass is
gone. However you may create the illusion of a more balanced sound by
removing also some high frequencies. But it's a downward spiral. Always
subtracting.

Same goes with snap&crackle: You may zoom in on that particular moment
when the snap is and *remove* the frequency range of the crackle. That
will make the snap go away - but you will never get back the sound that
*would* have been there had there not been a snap there in the first
place. If you catch my drift?

My tool of choise used to be Sony SoundForge, nowadays it's Audacity. I
have never tried Adobe audition so I can not give any advice on that
particular program, however as long as it is a suitable tool for the job
(and I assume it is) it doesn't matter that much what tool you use - the
important thing is to know how to use it.
And learning the tools require an understanding of what sound is made
of, from a technical point of view.

But it's fun while you learn! And if you got the patience and time for
it, just go ahead and try&fail your way to get to know both the tool and
the theory.

Just remember to never, never ever overwrite a source. Always work on a
copy. :)

Do you mind me asking what tools / filters and settings you have used successfully with Audacity?

Love as always, David

I am getting worried that I somehow has given the impression that I am a
"pro" when it comes to this, cause I'm not!

I'm pretty sure I just use what everyone else would think of as the
"obvious" filters related to restoration, and quite often I settle for
one of the presets, even.

There's one problem with naming them though: Since the default language
on my workstation is Norwegian, all the menus and names in Audacity are
in norwegian too. :D But I'll try to translate to what I suppose they
are called in english:

The three tools I'd say I *always* use are the compressor, normalizer
and equalizer. In my opinion you can get incredibly far by only using
the equalizer. Well, at least at my level of competence... :D

But then, all depending on the audio in question of course, I usually
fiddle around with the:
Click removal
Repair
Noise removal
Smoothen
Clip fix

Smoothen has taken some of the "edge" off the worst recordings, those
with a very aggressive, cutting sound. A nice tool. Noise removal too
has produced some pretty impressive work at times.

One thing I'd *really* love to figure out though, is how to do something
about the horrible noise that appears with audience applause if the
recording has been treated with heavy compression. Those "flick
flack"-sounding things... That's a noise that get on my nerves.
