Default De-fading audio

This one should be easy, I just wanna undo a faded-in/out part of the
audio. Hopefully MATLAB ain't required for this, 'cuz my copy arrives
in 2 weeks and I ain't waitin.

If the fades were done properly, what you will end up is
a cross-fade between your music and noise of equal
loudness.

Is that what you want?

Cuz this isn't pitch-shifting. I assume it isn't a science to boost
the first couple of samples by 5 dB, the 2nd by 4.99... you get the
idea. Just gradually raising the amplitude, just like you do the
opposite when you fade-in. If that's possible, then I don't see the
logic of the opposite being impossible. Then again, I'm not good at
logic.

Sure, I don't care. This is a song that starts with the host giving a
2-minute intro that for some reason is faded-in. I could give an ape's
ass if it'll distort a bit, as long as its straightened.

Or audio it would seem.

How deep is the fade ?

It's "industrial one", why would one expect anything logical?
Perhaps "Radium" on new meds (and a new alias).

Come to think of it, it's very much his style. Well spotted.

Radium doesn't use that kind of language. Possibly another Asbergers'
though.

Jakdedert seems to be knowledgeable on such matters around here.

And if the fades were NOT done properly, what you'll end up
with is a cross-fade between the music and VERY distorted
music.

And I'd bet that's not what you're looking for, either.

In otherwords, if what you're looking for is to completely
undo the fades and restore the audio to the way it was
before the fades, forget it. Ignoring how you'd try and get
there, what you're asking for is impossible.

There are 101 problems with doing this, not least raising the noise level
of the faded part.

If the original audio is properly dithered, it will fade down into noise.
When you de-fade it, you will end up with noise, not the original sound.

If the original audio is not properly dithered, it will fade down into
distortion. When you de-fade it, you will end up with distortion, not the
original sound.

Only at the very beginning where the signal may be close to the
amplitude of the noise which is like... 3 seconds. Wow. After that,
the signal is way above the volume of the noise floor, so I don't see
why you're so convinced that it'll scuzz my song up.

You didn't say how far down into the scuzz you were trying to reach. As long
as the signal-to-scuzz ratio is large enough, the sound quality might be
quite acceptable to you.

You need to supply DETAILS big time or *no-one* will be able to help you.
