The T-Racks CS comes with metering and Classic EQ for free.
 
A bit confusing though. Should the peaks be at -12db for K-12 metering or should the RMS level be at -12?

Is IK's website down?  I'm at work so could be getting blocked for some byzantine reason. 

ToneBoosters EBULoudness. Not free but cheap and awesome. Generates a time based graph. Great for getting all songs on a CD at the same volume.

Don't have background, and experience of most of you, but
+1 on the Kmeter nice size, easy to setup and use.
May be same as above, but my source was...

At about 20 min in the Klanghelm VUMT is also talked about.

I really like the T-racks metering. The perceived loudness meter is a pretty good tool for leveling tracks. +1 for the Toneboosters ebu loudness plugin. Demo mode is plenty good enough for that one. I also have and like...Klanghelm VUMT http://klanghelm.com/VUMT.html, Hornet VU meter, http://www.hornetplugins....ugins/hornet-vu-meter/ .    
 And Sleepytime dsp Stereo channel, http://sleepytimedsp.com/software/str-bundle/.

Absolutely awesome

Totally agree! Though not free it's worth the $12 or so. And it supports a really good indie developer. Klanghelm plugins are top notch!

Thanks John for posting this link. I've seen this before and it's wicked helpful!

You're welcome Southpaw.  That vid clued me in to just how good the VUMT is. And you're right Klanghelm is an outstanding developer.
