This is circuit schematic of audio low pass filter. By using this circuit for audio can filtering just low output frequency. Based on IC LM324 for filtering audio signal input to low frequency output. Power Supply need 9V up to 15V DC. Using DC Regulated power supply for more effieciency audio filtering and more low noise output.
