Passive filters | DIY-Audio-Heaven
https://diyaudioheaven.wordpress.com/headphones/passive-filters/
home updated: Jan-27-2022 Each filter is purpose made for a specific headphone (see list below) and can NOT be used for other headphones. There thus is no ‘universal’ filter. Passive filters can ONLY attenuate. (Substantial) peaks in frequency response are far more sound degrading than dips. This is what these filters do they remove emphasis…
Audio Filters: Designing an audio equalizer – Part 7
https://www.engineersgarage.com/audio-filters-designing-an-audio-equalizer-7-8/
Equalizers can be designed using audio filters or integrated chips (such as an LA-3600, which is a five-band equalizer IC). For this project, we’ll design a three-band, graphic equalizer circuit using audio filters. So, it will have low, high, and band-pass filter circuits to separate the low, high, and mid-range frequencies of the audio signal.
Mains filters | DIY-Audio-Heaven

For those into DIY …. C2 and C3 MUST be class Y type capacitors, they must be able to handle very high voltages, at LEAST as high as the peak voltages of RV2 and RV3. Very important for your safety! R1 doesn’t do anything for the filter action but is only there to discharge the filters capacitors when mains has been turned off.

In contrast, low pass filters can be used to filter out high frequency signals in audio being sent to subwoofers that can't efficiently reproduce the high-frequency parts of the audio signal. They are also used in devices such as in the tone knob of an electric guitar (to …

How to Build a Passive Bandpass Filter Circuit
http://www.learningaboutelectronics.com/Articles/Passive-bandpass-filter-circuit.php
A bandpass filter is needed if only a certain range of frequencies are needed. An example of uses for bandpass filters are audio applications if only certain frequencies are desired to be heard while others should not. This type of bandpass filter is a passive bandpass filter. It doesn't require any power. It is not used for any active ...

Filter. On the filter schematic by Mloyd1 if D1 and D3 are removed DC will be blocked and the capacitors still protected. The caps see very low DC because of the diodes. Make sure to use high ripple current capacitors. Digikey has some good for about 4 - 5 amps and you could use more of them.
