An audio filter is a type of filter used for processing sound signals. Many types of filters exist for applications including graphic equalizers, synthesizers, sound effects, CD players and virtual reality systems.An audio filter is typically designed to pass some frequency regions through unattenuated while significantly attenutating others. In some applications, such as in the design of graphic equalizers or CD players, the filters are designed according to a set of objective criteria such as pass band, pass band attenutation, stop band and stop band attenutation, where the pass bands are the frequency ranges for which audio is attenuated less than a specified maximum, and the stop bands are the frequency ranges for which the audio must be attenuated by a specified minimum.
In other applications, such as with synthesizers or sound effects, the aesthetic of the filter must be evaluated subjectively.
Audio filters can be implemented in analog circuitry as analog filters or in DSP code as digital filters.

An electronic filter eliminates unwanted frequencies from an electronic signal.A low-pass filter passes low frequencies. A high-pass filter passes high frequencies. A band-pass filter passes a limited range of frequencies. A band-stop filter passes all frequencies except a limited range. A notch filter is a type of band-stop filter that acts on a particularly narrow range of frequencies.
Band-stop and band-pass filters can be constructed by combining low-pass and high-pass filters.
A popular form of 2 pole filter is the Sallen-Key type. This is able to provide low-pass, band-pass, and high pass versions.
Passive Filters
The simplest electronic filters are based on combinations of resistors, inductors and capacitors. Since resistance has the symbol R, inductance the symbol L and capacitance the symbol C, these filters exist in so-called RC, RL, LC and LCR varieties. All these types are collectively known as passive filters, because they are activated by the power in the signal and not by an external power supply.
Here's how passive filters work: inductors block high-frequency signals and conduct low-frequency signals, while capacitors do the reverse. A filter in which the signal passes through an inductor, or in which a capacitor provides a path to earth, therefore transmits low-frequency signals more strongly than high-frequency signals and is a low-pass filter. If the signal passes through a capacitor, or has a path to ground through an inductor, then the filter transmits high-frequency signals more strongly than low-frequency signals and is a high-pass filter. Resistors on their own have no frequency-selective properties, but are added to inductors and capacitors to determine the time-constants of the circuit, and therefore the frequencies to which it responds.
At very high frequencies (above about 100 megahertz), sometimes the inductors consist of single loops or strips of sheet metal, and the capacitors consist of adjacent strips of metal.
Other components can be added to LC filters to make them more precise.
Filters are measured by their quality or "Q" factor. A filter is said to have a high Q if it selects or rejects a narrow range of frequencies compared with the absolute frequency at which it operates. Quality can be measured by the precision of a harmonic oscillator implemented with that type of device.
Active Filters
Filters can also be implemented using a combination of passive components and amplifiers to create active filters. These can have high Q, and achieve resonance without the use of inductors. However, their upper frequency limit is lower than that of a passive filter. Further detail is available in the digital filter section.
Other filters
In the late 1930s, engineers realized that small mechanical systems made of rigid materials such as quartz would acoustically resonate at radio frequencies, i.e. from audible frequencies (sound) up to several hundred megahertz.
Some early resonators were made of steel, but quartz quickly became favored. The biggest advantage of quartz is that it is piezoelectric. This means that quartz resonators can directly convert their own mechanical motion into electrical signals. Quartz also has a very low coefficient of thermal expansion. This means that quartz resonators produce stable frequencies over a wide temperature range.
Quartz crystal filters have much higher quality factors than LCR filters. When higher stabilities are required, the crystals and their driving circuits may be mounted in a "crystal oven" to control the temperature. For very narrow filters, sometimes several crystals are operated in series.
Engineers realized that a large number of crystals could be collapsed into a single component, by mounting comb-shaped evaporations of metal on a quartz crystal. In this scheme, a "tapped delay line" reinforces the desired frequencies as the sound waves flow across the surface of the quartz crystal.
The tapped delay line has become a general scheme of making high-Q filters in many different ways.
Lately, for lower frequencies, digital signal processing has been able to inexpensively construct very high Q filters. In this scheme, a computer program simulates a tapped delay line. An analog to digital converter turns the signal into a stream of numbers. The computer program stores the numbers in a list in the computer's memory. Then, the program selects numbers from this list, at a spacing that simulates the comb of a tapped delay line. These numbers are multiplied by constants, and added together to make the output of the filter. The filter's output becomes a signal by passing it through a digital to analog converter. There are problems with noise introduced by the conversions, but these can be controlled and limited for many useful filters. Digital signal processing is especially useful for audio.
Another method of filtering, at frequencies from 800 megahertz to about 5 gigahertz, is to use a synthetic single-crystal garnet sphere made of a chemical combination of titanium, iron and nitrogen. The garnet sits on a strip of metal driven by a transistor, and a small loop antenna touches the top of the sphere. An electromagnet changes the frequency that the garnet will pass. The advantage of this method is that the garnet can be tuned over a very wide frequency by varying the strength of the magnetic field.
For even higher frequencies and greater precision, the electrons of atoms must be used. Atomic clocks use cesium masers as ultra-high Q filters to stabilize their primary oscillators. Another method, used at high, fixed frequencies with very weak radio signals, is to use a ruby maser tapped delay line.

A filter is a membrane or layer that is designed to block certain things (objects or substances) whilst letting others through. Filters are often used to remove harmful substances from air or water, for example to reduce air pollution or to make contaminated air breathable with a gas mask. Very common is the coffee filter. In mathematics, a filter is a subset of power set with certain properties. See filter (mathematics). A filter is a short-form of mail filter. An electronic filter is an electrical circuit whose frequency response or transfer function is non-uniform. In other words, its gain or attenuation depends on frequency. An analog filter is a form of filter (usually electronic) that uses analog circuitry in its implementation. A digital filter is an algorithm for processing numeric data, and which can also be used in digital signal processors to function in a similar way to an electronic filter. Digital filters are now used in many modern appliances, such as CD players, radio tuners, TVs etc. An audio filter is a type of filter that is used for processing audio signals in appliances such as CD players, synthesizers or sound effects. A 1990s industrial rock band is called Filter. An optical filter removes/only passes certain wavelengths of light, e. g. Infrared filter, ND filter, UV filterSee also: Glossary of filter terms

Filter is an industrial rock band that gained some mainstream acceptance in the 1990s, along with similar artists like Garbage and Marilyn Manson. Richard Patrick and Brian Liesegang formed the band in 1993, releasing Short Bus in 1995. The album was a hit, but the band was not able to capitalize on their newfound fame and Liesegang left in 1997. Patrick has continued on with Title of Record in 1999.Filter's first mainstream hit, "Hey Man, Nice Shot", off the album "Short Bus", was highly controversial as it was seen as capitalizing off the public suicide of Budd Dwyer.

A filter F on a set S is a set of subsets of S with the following properties:
A simple example of a filter is the set of all subsets of S that include a particular subset C of S. Such a filter is called the "principal filter" generated by C. The Fréchet filter on an infinite set S is the set of all subsets of S that have finite complement.
- S is in F.
- The empty set is not in F.
- If A and B are in F, then so is their intersection.
- If A is in F and A ⊆ B ⊆ S, then B is in F.
Filters are useful in topology: they play the role of sequences in metric spaces. The set of all neighbourhoods of a point x in a topological space is a filter, called the neighbourhood filter of x. A filter which is a superset of the neighbourhood filter of x is said to converge to x. Note that in a non-Hausdorff space a filter can converge to more than one point.
Of particular importance are maximal filters, which are called ultrafilters. A standard application of Zorn's lemma shows that every filter is a subset of some ultrafilter.
For any filter F on a set S, the set function defined by
is finitely additive -- a "measure" if that term is construed rather loosely. Therefore the statement
can be considered somewhat analogous to the statement that φ holds "almost everywhere". That interpretation of membership in a filter is used (for motivation, although it is not needed for actual proofs) in the theory of ultraproducts in model theory, a branch of mathematical logic.
Filters as described above are subsets of a particular lattice, namely the power set of S. Filters can be also be defined in other lattices - see lattice for details.

A filter program is classically a UNIX program that is designed to be used as part of a pipeline of two or more UNIX utilities. Generally a filter program will read its standard input and write to its standard output and do little else. Conventionally a filter program distinguishes itself by being fairly simple and performing essentially one operation, usually some sort of simple transformation of its input data.The classic filter would be grep; here's an example:
cut -d : -f 1This finds all registered users that have "foo" as part of their username.Common UNIX filter programs are: cat, cut, grep, head, sort, uniq and tail. Programs like awk and sed can be used to build quite complex filters because they are fully programmable.
A more complete list of UNIX filter programs:
- awk
- cat
- comm
- cut
- expand
- compress
- fold
- grep
- head
- nl
- pr
- sed
- sh
- sort
- split
- strings
- tail
- tee
- tr
- uniq
