What's the best way to clean up the audio in Sonar?

Annabelle,
 
It may be that the tape itself is just deteriorated, or has been near a
magnetic device like a computer display, TV set, or phone charger, and
itself has become slightly magnetized. Nothing you can do except capture the
audio and try to clean it up with Sonar or Sound Forge. The older a magnetic
tape gets, the more it is affected by pervasive EM radiation in our
environment.
 
That's why old VHS tapes start to look bad, even if they've never been
played. They are affected by the earth's magnetic field, a constant
unidirectional field that pounds on us 24x7. If those tapes are precious,
they need to be archived to an optical or flash media form.

I've tried the fast forward and Rewind, but it didn't change anything. I had
recorded this tape in 2007, but I hadn't listened to it but maybe once or
twice since then.

Annabel,
 
This is more likely due to your tape having stretched or being wound
loosely, causing the variance in volume. Have you done a fast-forward and
rewind a couple times, to "settle" the tape?
 
If it still has volume variance, then it could be an old tape.
 
I have a demagnetizer cassette for my standard-size cassette, but have never
seen one for a micro cassette. You may have to take your player to a repair
shop and have someone use a hand-held demagnetizer. Just be sure they know
what they're doing, or you can really mess up or damage your playback heads,
if not done properly.

Hi, it's Annabelle.
I'm wondering, what's the best way for a blind customer like me to
demagnetize a Microcassette Recorder? The reason why is because I want to
convert one of my microcassettes to a digital recording in Sonar, and I
don't want it to sound like the volume keeps going up and down all the time.
Anybody have any suggestions for me?
