Reg: audio input/output

just started playing with the program, so i apologize if this is a dumb question…

is there a way to split the audio by frequency, so that certain aspects are affected by the bass while others are affected by the treble? (honestly im looking to get down to individual Hz here, but ill take what i can get)
im looking to push the audio-reative elements of this program to the limit for live sound production.

thank you in advance and namaste

ok. update…

i get the basics. like using the fft, but i cant figure out how to change the value and range of the 4 spectrums it has to offer

Map (Value) node could be helpful
