Audio Filter Circuit - Engineering Projects
https://bestengineeringprojects.com/audio-filter-circuit/
An audio filter circuit is a broadband filter and is also called a wide bandpass filter because its bandwidth is restricted to the audio frequency. Audio filter circuit can be formed by simple cascading high pass filter circuit and low pass filter circuit and is generally the choice for simplicity of design and performance through such a circuit can be realized by a number of the …

If your main amplifier’s sound is not clear as low treble and little bass then this circuit is easy and very simple to use has less equipment. This circuit is used to add bass, more during the normal listening levels. It is a passive circuit and does not use the power supply. Hardware Required Circuit Diagram Working Explanations

The low pass filter can be made as follows: Input - Resistor - (Output) - Capacitor - Ground Low pass filters filter out signal with frequencies above the cutoff frequency (1/2πRC). Since the cutoff is strictly determined by R and C, choose the appropriate resistor and capacitor to cutoff frequencies where you want to
