Wow! Thanks! I can definitely do that. I just got done reading Level Practices (Part 2)
Level Practices (Part 2) (Includes the K-System)
and am sold on the idea. I'm getting a radioshack spl meter this afternoon when my wife finishes her errands and relieves me from baby duty

I was wondering if the RMS metering would be enough to let me know where I am? I use Logic 8, so the metering in there is pretty thin - I can get peak and rms on the same display, a more basic version of what T-Racks is showing in their metering.
Is it as simple as calibrating my monitors for 83db using a -20dbfs test tone? I obviously need to re-read the paper, as I realize while typing this that I'm fuzzy on what exactly the steps are to implement this. I want to mix at k-20 and shoot for mastering projects (when I do an in-house job) for k-14...
