[LAU] Request for open source solution to spectrograms and phase measurement

Sorry for the crossposting, but I don't know which list is more suitable to what I'm asking. One friend of mine is looking for a solution based in Linux. I admit I don't understand fully what he needs. That's why I am asking to you gurus out there... :) He needs something for level measurement of spectrograms, callibrated as K-14, also for phase measurement. He used [1]a plug-in for Nuendo in the past, but now he's looking for a netbook devoted only to this task, and he wants to use an open source solution. 1. http://www.nugenaudio.com/visualizer.php Any suggestions welcome.
