    hi, i am looking for an audio frequencies low pass filter.
    i would like the filter to cut-off the audio frequencies above 5Khz.
    do you have any schematic?

    What power levels are we talking about here? If it is in a preamp section then you should make an active filter using op amps use this TOOL. If it is post amplifier and needs to handle high power then your filter will be huge because you will need large Caps/Inductors.
