I have applied the cakewalk spectrum anaylzer to the effects bin of various tracks to look at the freqs used and look for any that i can remove. I make changes for example apply a HP filter at 80 hz with -24 db. the I can hear the differrence but the analyzer doesn't indicate the change. What is the correct way to use the spectrum analyzer so it will indicate the post eq audio accuratly? Perhaps I need to get a better analyzer plug?

Are you sure you have the spectrum analyzer inserted in the chain after the eq.

well...the analyzer is in the fx bin and I am using the prochannel eq and its set to Post FX Bin = no, so that implies it is pre-fx bin so I think i have it correct.

Try placing the analyzer on the Master buss, just for integrity, and solo the channel you're EQ'ing. Some EQ plug-ins will give you a directly viewable spectrum analyzer, such as DMG Audio's EQuality.

I just tried and was able to see the reduction in the analyzer. Try some very extreme eq. settings and set the analyzers resolution to "Hi". Sorry I'm not anymore help. Hopefully someone will chime in who can be more help.

What was your slope setting? If it's low then you're still going to see a fair amount of activity below your cutoff point. Also I have found that the console emulation adds some low frequencies as well so try turning that off to see if it makes any difference. 

the cakewalk analyzer does not accurately reflect frequency cuts, esp in low ranges, and i would be wary because of this that it accurately reflects activity across the frequency range.  here's a screenshot showing cake's analyzer and blue cat's after a 96db/oct filter was applied to a track...

Yeah I would ditch the Cakewalk one and get either the Bluecat analyzer or Vonexgo Span. They are both excellent. 

I recently installed both the Blue Cat analyzer and the Vonexgo Span and they don't display the same thing. Makes you wonder who is right.

don't disagree. 

from the help file...

Lower resolution yields faster updates but less accurate low frequency analysis. Higher resolution yields much better low frequency analysis but slower updates.
