This audio noise filter circuit is a bandpass filter for audio frequency band. It filters unwanted signals that are lower or higher than the audio frequencies. It has 2 filters: a low pass filter and a high pass filter in a cascade configuration. Both filters are second-order filters with a 24 dB/octave fiter capability.

It forms a Sallen-Key Butterworth active low-pass filter. Its cut-off frequency of 5kHz is determined by capacitors C4, C5 and C6. It restricts the audio response and filters out unwanted noise by attenuating frequencies higher than 5kHz. Resistor R6 and capacitor C7 give a clean supply voltage to the op-amps.

Live Audio/Music: Band-stop filters are frequently used to eliminate or reduce feedback from amplification equipment by impeding a narrow frequency band (sometimes referred to as a “notch”) and thereby preventing the development of the feedback loop and resulting sound. High-pass filters are also frequently employed to clean up audio signals from …

The circuits will be active filters using an operational amplifier (op-amps). The gain for each frequency band will be regulated using variable resistors, connected at the filter circuits’ input. The different frequency components will be combined at the filters’ output stage and connected to an LM386-based power amplifier circuit. The amplifier circuit will boost the combined audio …
