Spliting a recording into hi mid low

[gitRhero]

I'm working on cleaning up some old cassete recordings and I read somewhere it's a good idea to split the recording up into lows mids and highs so it's easier to work with.
My question is what would the best frequency range be for the lows mids and hi's?
e.g.
lows o-500
mids 500-6000
highs 6000-inf
Something like that? What would be the best place to split the frequencies?

Hope this ? makes sence...
Thanx J

There's no way to answer that, as it will depend entirely on the frequency distribution of the material you're trying to "rescue".....

In other words - there's no way around the fact that it's context-sensitive so you have to use your ears!

Sadly I've had to do a lot of that. Ah, those good ol' days of boombox recording.

What I did is use a parametric EQ to help identify problem frequencies. Crank it all the way up and then sweep until you find the frequencies that are the problem. Then split in between those frequencies. A combo of narrow deep cuts on those frequencies and judicious use of compression on each band does the trick.

This is kind of a brutal technique so I save it for rescue missions.

Thanx for the replys guys not sure if you understand my question though.
What I'm talking about is making 3 seperate tks of the recording
one containing only the low end, one the mid range and one the highs...
I've been doing this by using a low pass at say 500, so all I have left is the low end, that would be saved as trk 1
then a hi-pass at 500 and a low-pass at say 6k for trk 2
then a hi-pass at 6k for trk 3
Then I would have 3 seperate trks on the mixer ready for EQ and other treatment.
That way for example you can compress the bass, kick etc without effecting the mid/hi range.
I guess if I experiment enought I'll find the best frequency is range for each trk.
Maybe I should just ask it like this, what is considerd low end 0-500?? Mids 500-6k?? 500-3k??
Hi's 3k-inf 6k-inf??? 10k-???

Thanx

Starting points -

Top of the lows - 100-150

Top of the mids - 2-3k

Top of the highs - Whatever the top is.

Again - Those are just starting points... As mentioned, it's a VERY context-sensitive operation.

Or, just use a multi-band compressor (same starting points apply).

Wouldn't a multi band compressor do the trick?
