Ultra-simple low pass audio filter? Answered
Is there a way to create an ultra-simple low pass filter? Will not be using it for subwoofer, but to split audio and boost the power for audio-synced leds. Is a split at about 15-200 hz any good? or should it be higher/lower. Mostly looking for bass guitar and some drum to go in this area. I am totally non-audio knowleged, and am beginning my circuit building skills, so yes, i need lots of help. Can i hook this in parallel to speakers and will it not affect sound quality? can i use a separate audio (no op-amp) amp to boost power to leds? (such as a .5w amp to leds that consume less than .5w?) or should i find an op-amp. Could i just put the filter on and hook leds up in parallel w/out sound loss? I am getting totally lost. I know this is a LOT to ask of you, but your answers to my previous questions have been very helpful and are greatly appreciated. Thanks for putting up with me :) I wish i could figure this out better, but i am having a hard time. So far example no.1 on this link (about halfway down page) seems to look pretty good. Thanks!!!!
