In answer to your original question, you could get a copy of Audiofile Engineering's
'Spectre' plug-in bundle here
It's a very useful bunch of audio analysis plugs, but
the relevant point in this instance is that you can re-size the plugs - so for tracking,
you could have a peak / overs meter the size of a 30 inch screen if need be. Probably
enough to be seen from anywhere in the room you're playing and recording in.
