There is a pretty good article MSGEQ7-Based DIY Audio Spectrum Analyzer: Construction at eetimes.com. This is where I got this timing diagram from: We can read the MSEQ7’s signal at the times shown in green. The output of the MSGEQ7 is connected to the input of the LM3915 which controls one 10-LED bar graph display at a time.

11,249. Dec 2, 2008. #17. The input of the LM3915 does not need a clamp. It is safe with an input as high as + 35V or -35V. The datasheet for the LM3915 (and I) recommend using a peak detector circuit to hold the display reading for a moment so that you can see a peak. The datasheet has a few peak detector circuits.
