This is amazing!!! Wow!!! Great work , Olafk!
Could you please tell what is the total cost and power consumption of this project?
Merry Christmas!

The total cost is round about 100 Euro without PCBs. It needs 2 PSU. 8V for LEDs (apr. 3...3,5A) and +/- 15V for preamplifier (150 mA). But only if you can produce your own PCBs.

Hi olaf,
I want to make an audio spectrum analyser following you.
Could you kindly help me with your board layout and schematic in pdf format?

Dear Olaf,
I found a nice display section with more LEDs on youtube
10 band audio spectrum analyzer with 400 LED FullHD - YouTube
This section uses LM324 opamps.
The poster posted a documentation link there too.

I want to use this display section along with your filter section.
It would be great if you could confirm it will work or not.
Thank you. 🙂

Here is some info on a 2x15 and a 1x40 VU meter using an inexpensive PIC16F88. Add proper filters in front (for 1/3 octave you will need a 6-pole Butterworth for each band): www.s-o.webnode.cz/vu-meter/ E
