While scouting the forums I found this gem of a problem . Personally I love tinkering with music, I spent probably 3 4 months playing around with the Audio Plug...
I made a quick update in the C3 file so the bars increases when the beat hits instead of shrinking, everything else is the same, for those that have the C2 file you might want to change the ---------------| Action on line 5
from
------------| 10 plus abs((Audio.AnalyserFreqBinAt("music",0,Self.binNR)*Gain))
to
------------| 250 plus ((Audio.AnalyserFreqBinAt("music",0,Self.binNR)*Gain))
it will react a bit better.
Those that have C3 version just redownload the file.
If you don't want the big gaps between bars you can change the condition on Line 5 from > to >= and that will make all bars dance all time while still react a bit better but isn't a big difference at that point from the default Construct Audio analyser template.
