I am looking for a program that measures frequency response, harmonic distortion etc from LINE-IN. I'm trying to make the graphs for comparison of different mp3 players. Any ideas?

Yes I know I can google for some, but I'm wondering if there are ones that are popular (for accuracy, or ease of use, or ease of interpreting the results...)?

I normally use ARTA ARTA home.
