RBJ Bandpass1A Filter Project
My first custom DSP Code Filter.
A slightly modified version of the RBJ Bandpass1.hom File
I added a gain control pin and adjusted the response.
Also built a special versatile amp mod for it.
Has volume output, dB linear scale 1-10 gain control, 0.01-3 gain resonance/Q control and is default set at 440Hz (A note) with 110-8800Hz bandwidth range.
I tested it both with audio signal and the schematic included frequency analyzer and it has decent level stability. It has ample warmth and pleasing tone.
I plan to 'tweak' the RBJ Low & Hi Pass Filters similarly.
