A bit of internetting tells me the low-pass filter will filter out noise above a specific frequency, and provides links to calculators that show the affect of different resistor / capacitor pairs.
Applying a low pass filter in the frequency domain means zeroing all frequency components above a cut-off frequency. This is similar to what one would do in a 1 dimensional case except now the ideal filter is a cylindrical "can" instead of a rectangular pulse. This filtering allows you to adjust only the low frequency, or bass, by amplifying the output of your filter, which will only be the low frequencies. Similarly, you would use a highpass filter to do this to the higher frequency, or treble, in your music. The filters used in audio applications are much more complex than the example provided here. .
This tutorial describes the structure and behavior of a low-pass filter. Why do you place a low-pass filter on your mix in the 17kHz-20kHz range? I've been producing for a few years now and it hasn't been until recently that I've come across forums and videos of producers taking about low-passing their mixes in the 17kHz-20kHz range. Hi, I use the "Q-Bandpass" measurement to evaluate the Q factor of a Low pass Sallen Key filter (2nd order). If the response presents an overshoot (Q>1), this evaluation works fine but when there is no overshoot because Q is < 1, PSPICE is not able to evalute it.
High Pass Filter passes frequencies above its cutoff frequency and attenuates frequencies below its cutoff frequency. This effect can therefore be used to reduce low frequency noise.

When you’re done mixing the volume level of the hihats, you usually don’t really have to boost or cut anything. Still, the clank or gong sound is around 200 Hz, but if you want definition, then roll off everything below 500-600 Hz using a high-pass filter. By doing so, you clear out low-end information that is nonessential for the hihat. At low frequencies the opposite is true. If we take the potential difference across the resistor to be the output voltage, the output voltage is high at high frequencies and low at low frequencies. This is a high-pass filter - high-frequency signals pass through virtually unchanged, but low-frequency signals are attenuated.
Passive Crossovers. A passive crossover has no active filters as were used in the electronic crossover. It uses coils (inductors) and capacitors to cause a rolloff of the audio level above or below certain frequencies to prevent unwanted portions of the audio from reaching the various speakers. Typical filters are low pass, high pass, and band pass. An equalizer (EQ) is a type of filter that corrects for losses in the transmission of audio signals, making the output equal to the input, or making an otherwise inconsistent frequency response "flat," giving all frequencies equal energy.
catalog low pass filters. These LPF’s incorporate DLI’s high dielectric ceramic materials which provide small size and minimal performance variation over temperature. The catalog LPF’s are offered in a variety of frequency bands, which offers a drop in solution for high frequency attenuation. FEATURES Small Size Band pass filters with narrow bandwidths require components with high precision and Q. Bandwidths less than 10% of the center frequency can be difficult or even impossible to implement with discrete LC components. Your mileage may vary. Bandpass filters with a bandwidth wider than one octave may not perform as expected.
The upper post connection is a high pass filter at a corner frequency of 2.3kHz and the lower post connection has two low pass filters one has 2.3kHz corner frequency and the other has 200Hz corner frequency. The components used are of ordinary (or low) grade. The inductors use insulated single copper wire. If you must apply a shelving boost, also use a 20-30Hz high-pass filter for safety. LF shelving filters also continue acting, to some degree well beyond their specified frequency, so if you find you've collected excess low mid-range baggage while trying to boost the true low end, a compensatory peaking cut at 200-400Hz may be in order.
Jul 30, 2011 · Low Pass Filter - How do they work - Part I So I dance around this issue a lot because filtering is so important both in sound and radio implementations.

The Sallen-Key filter is a very popular active filter which can be used to create 2nd order filter stages that can be cascaded together to form larger order filters. High-Pass Filter passes frequencies above its cutoff frequency and attenuates frequencies below its cutoff frequency. This effect can therefore be used to reduce low frequency noise. Accessed by: Effect > High-Pass Filter... Sound below this cutoff frequency in Hz is not eliminated but increasingly attenuated as the frequency falls further ... RC Low Pass Filter. Since capacitive reactance decreases with frequency, the RC circuit shown discriminates against high frequencies. The circuit is an AC voltage divider with an output which falls off at high frequencies at the rate of 6 dB per octave.
Oct 31, 2014 · Abstract: When Fourier series are used for applications in physics, involving partial differential equations, sometimes the process of resolution results in divergent series for some quantities. In this paper we argue that the use of linear low-pass filters is a valid way to regularize such divergent series.
It is commonly thought that there will always be a phase difference of 180° between the outputs of a (second order) low-pass filter and a high-pass filter having the same crossover frequency. And so, in a 2-way system, the high-pass section's output is usually connected to the high frequency driver 'inverted', to correct for this phase problem.
