Low-Pass Filters - Analog Devices
https://www.analog.com/en/products/analog-functions/filters/low-pass-filters.html
Low-Pass Filters from Analog Devices are specifically designed to reject higher frequency noise and unwanted signals while allowing desired signals to pass through. Analog Devices offers an extensive line of continuous time and clock tunable (switched capacitor) devices preconfigured for low-pass filtering. These integrated low pass filters feature

Audio Filters: Designing an audio equalizer – Part 7

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.)

sr = 221e3; srDesired = 44.1e3; order = 8; passBandRipple = 1; %//dB Wp = 0.8 * (srDesired/2) / (sr/2); [b,a] = cheby1 (order, passBandRipple, Wp, 'low'); freqz (b,a, [],sr, 'half'); sos = tf2sos (b,a) This gives us an 8th order IIR filter with a …
8th-Order, Lowpass, Butterworth, Switched-Capacitor Filter
https://www.maximintegrated.com/en/products/analog/analog-filters/MAX7480.html
Description. The MAX7480 8th-order, lowpass, Butterworth, switched-capacitor filter (SCF) operates from a single +5V supply. The device draws only 2.9mA of supply current and allows corner frequencies from 1Hz to 2kHz, making it ideal for low-power post-DAC filtering and anti-aliasing applications. The MAX7480 features a shutdown mode, which reduces the supply …

High-Pass Filter. On the other hand, a high-pass (or low-cut) filter will remove frequencies below a given threshold. For many producers, this has become a go-to step to give clarity to the mix. Low-cutting most elements except your kick and sub-bass between 60 Hz and 120 Hz will help tighten up the low-end.

It offers "Variable 22 - 300 Hz low pass frequency control" Believe if you replace the audio caps C5 and C6 (may have to change C1, C2, and C7 also) with 10x the value, you get "2.2 - 30.0 Hz low pass frequency control". A schematic is shown on the site. pjrc September 18, 2017, 8:53pm #9. chris-h:

Low Pass Active Filter by LM741. When you want to filter low frequency gives can change only. I thinks the Low Pass Active Filter circuit help you. Because of it uses IC LM741,then usable easy follow circuit image. We can fix the frequency is cut off get, by equipment value R1=R2 = R , and C1=C2=C When fix give 50Hz frequencies low only that can change.
