Hello
I'm building my own home audio system, and I would appreciate some help.
I want to make a peak meter, based on the circuit shown on this page (Thank you jrz126)
https://www.electro-tech-online.com/threads/lm3915-help.13142/
But I wanna make a bar for each octave, for example 60, 80, 120, 240, 1K, 3K, 8K, 15K, etc. like the professional analyzers. I think mayble putting a high-pass or lo-pass filter on the entrance of each LM3915 I could do the job. But I don't know what value of condensers / coils to use. Or am I totally wrong?
Thank you very much, in advance!!!
