Audio Filters: Designing an audio equalizer – Part 7
https://www.engineersgarage.com/audio-filters-designing-an-audio-equalizer-7-8/
The low-pass filter is designed using a capacitor (“C2” in the circuit diagram) of 100 nF and a resistor (“R1”) of 3.2 kilo-ohms. Given these values of the capacitor and resistor, the cut-off frequency of the filter can be calculated as follows: FH= 1/ (2πR2C1) FH= 1/ (2π*3.2k*100n) FH= 500 Hz (approx.)
What is "Low Cut Filter"? - inSync
https://www.sweetwater.com/insync/low-cut-filter/
Low Cut Filter. Also known as a high pass filter. Basically this is a type of filter that removes low frequencies from an audio signal. Normally they are designed so they remove frequencies below a certain determined frequency (often somewhere between 20 Hz and 150 Hz).

The most useful filters with ease of use and best all-around performance are the Sallen Key active filters. Sallen Key filters are two-pole filters, meaning they have two reactive components (capacitors). All of the circuits below are based on this design. Low Pass Filter. In a low pass filter, frequencies above a certain point are blocked:

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 …

https://www.homemade-circuits.com/design-high-pass-filter-circuit-quickly/
As the name suggest low pass filter circuits are designed to pass or conduct a preferred range of frequency lower or below a desired cut-off threshold, and attenuate or gradually block the frequencies above this value.

the frecuency of your filter changes depending on what device you connect them as an example if you connect it on the xlr input of the mixer it will filter frecuencies about 100 hz and lower but even on the same mixer if you connect it on the "line input" it will filter frecuencies lower than 22 hz, so investigate the input impedance of the …

Audio Filters: Understanding the filters - Part 5
https://www.engineersgarage.com/audio-filters-basics-of-audio-filters-5-8/
A circuit of a first-order, passive low-pass filter. This equation provides the cut-off frequency for this filter: fl = 1/ (2πRC) The passive low-pass filter allows all frequencies lower than the cut-off frequency to pass but attenuates those higher than the cut-off.
Low Pass Filter - Passive RC Filter Tutorial
https://www.electronics-tutorials.ws/filter/filter_2.html
A Low Pass Filter is a circuit that can be designed to modify, reshape or reject all unwanted high frequencies of an electrical signal and accept or pass only those signals wanted by the circuits designer In other words they “filter-out” unwanted signals and an ideal filter will separate and pass sinusoidal input signals based upon their frequency.
