While thinking about the swept filter + sample and hold, I see an inherent problem. It has to do with display update rate. At the lower frequencies in the band, it will require a good length of time to get a good sample. Consider at least one period for each frequency (at 20Hz would be 50ms..and so in in whatever octave resolution you desire. By the time the full audio spectrum is swept, it may have been 400ms or so (just guessing here). That is a very low update rate for a VU meter, I believe it would not be tolerable.

I'm pretty sure that the Zetex product is obsolete --this chip isn't for that purpose. check other threads.
