Is there a spectrum analyzer that can go in the audio path for surround sound for both DD5.1 and DTS?

I am just looking for a simple box to display (level meters) whats going on, not an EQ.

Thanks!

I've never used anything other then a 2-channel meter, but I can vouch for Dorrough quality, though.
perhaps this is what you are looking for.

Dorrough

Cheers.

Thanks but they are a bit pricey...I think I found what I need. Thanks!
