/diy/ - Do It Yourself

find a high-pass filter calculator on the interbutts. plug in your component values to see what frequencies will be accepted or rejected. so, in your example, i use 50K (coz you have 2 paths of 100K each to the power supply) and 100nF, and it tells me it'll allow frequencies above 32Hz to pass. this sounds fine for audio.

i ignore the 5K resistors coz they have no business being there in the first place. if you wanna protect things from other things, try something around 470-ohms.

as for that other 5K from 3.3V, that makes no sense in your context.
