so I can have some LEDs be made brighter or dimmer depending on which frequency
to pick out lows, mids and highs...
I want to be able to somehow connect an arduino to an audio from my sound system etheir by mic or tapping into it before the audio goes into the sound system to be amplified.
I could do something like make the led brighten if some thing is played low is played but is there a way to also detect the volume of the pitch. So instead of more pitches being played to brighten it but also to have the volume of it integrated as well. So some LEDs would show up more than others at different times of a song?
