Bandstop filters with high Q factors are also called notch filters. Build a simple notch filter. Using a resistor, a capacitor, and an inductor, you can build a simple notch filter as follows: What frequencies does it filter? The center frequency, also called the resonant frequency, around which this circuit will filter can be found as
Audio Noise Filter Circuit - ElectroSchematics.com

P. Marian. audio filters. NE5532N. 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.
A Passive LC Audio Filter For Amateur Radio Use
http://www.genebitsystems.com/david/AudioFilter/A_Passive_LC_Audio_Filter.pdf
External audio filters are sometimes used to improve the selectivity or enhance the audio quality of amateur radio receivers. These filters are usually implemented as op-amp active filters, switched-capacitor filters, DSP-based filters, or some combination thereof. Another possible and much older filter implementation approach uses a combination of
