we're all happy it works. but now it's time to abandon it and redo it properly.
1) make the filter steeper, say 4-th order instead of 2-nd order
2) rectify and filter the output, so you get a DC level equivalent to the peak amount of base, but smoothed (average over time) so it looks aesthetically pleasing.

this means you need very little coding, just read a voltage and display something that reflects that value.
