Anti-hum filter circuit for 60 Hz - Analogfilters
https://www.analogfilters.com/anti-hum-filter60hz/
Anti-hum filter for 60 Hz The anti-hum filter is a notch filter and can be used to suppress the unwanted hum tone which can have been interfered by the electrical grid. This design is for a utility frequency of 60 Hz. Settings Frequency …

After the volume pot of the stereo amp, on the "hot" wire solder serial capacitor on each channel. If the amp input impedance is, say, R=47 K, then for f=60 Hz you need C=56 nF - very small and very cheap. Varying resistivity of the volume pot will have some interactivity with the high-pass filter, but if you use 5 - 10 K pot everything will be OK.

Low-cutting most elements except your kick and sub-bass between 60 Hz and 120 Hz will help tighten up the low-end. Low-cutting a hat loop with unnecessary low-end information However, beware of applying too many high-pass filters. Consistently removing the low-end from your sounds can remove their body and punch.

Eliminate the 60 Hz noise using a Butterworth notch filter. Use designfilt to design the filter. The width of the notch is defined by the 59 to 61 Hz frequency interval. The filter removes at least half the power of the frequency components lying in that range. d = designfilt ( 'bandstopiir', 'FilterOrder' ,2, ...

The 60Hz notch filters were modeled by a 1st order and 2nd order digital filter. In both cases, whether with 10% or 100% 60Hz noise, the 2nd order digital filter doubled the noise attenuation compared to the 1st degree filter as summarized in Figure 5. Figure 5.

And are there better resistor capacitor pairs than others for just doing a standard high pass filter? I tried a 1uF cap and a 100ohm resistor in a high pass formation and it seems to get rid of 60 Hz noise, though I am a bit nervous about the other signal it might be killing off as the 1/2(pi)RC for the pair is 1.5kHz as well as some inconsistent phase shift it might produce if I …

Active notch filters were actively used during the earlier decades for amplifier and audio applications for eliminating of 50- and 60-Hz hum interferences. These networks have been although somewhat awkward from the standpoints of center notch frequency (f0) tuning, balance, and consistency.

Eart Audio Editor is a free audio filter software for Windows. In this software, you get multiple audio filters namely Band Pass, High Pass, Low Pass, High Shelf, and Low Shelf filters. The bandpass filter allows you to set upper and lower frequency threshold values according to which it filters out the audio frequency.
How to Build Audio Filter Circuits - Circuit Basics
https://www.circuitbasics.com/audio-filters/
An audio filter is a circuit that has been designed to let certain audio frequencies pass in a signal but block other frequencies out. One example of an audio filter is the cross-over module in a loudspeaker box. It sends low frequency sounds to the woofer and blocks them from the tweeter. Other uses might include blocking low-frequency rumble ...
