Parametric Equalizer

A parametric equalizer allows you to have more control over the parameters of tone on an instrument during recording. It has knobs that allow you to manually adjust the parameters of the tone. In other words, you can fine tune the tone of an instrument with a parametric equalizer. They used to be used mainly by professionals but now they are used for home theater systems too.

The parametric equalizer was developed in the late 1960s. Prior to its development sound technicians were very limited in their attempts at trying to improve the tone of an instrument in a recording. This is because all they had to use were preset shelving filters and graphic equalizers. A parametric equalizer gives the sound technician more control over tone than a graphic equalizer does. The parameters the sound technician has to work with when using a parametric equalizer are frequency, bandwidth and boost. This means they can control the frequency, alter the number of octaves and the amount of signal strength. A sound technician can also remove extraneous noises from the recording as well.

The parametric equalizer helps to improve the frequency of any instrument that is not “speaking” well during a recording. This helps the instruments that have a lower volume than others and are not being picked up as they should. Now sound technicians can precisely tune the sound signals. They can shift the center of frequency with a parametric equalizer and widen the band of frequency if they need too. Because of the parametric equalizer we now enjoy the quality and clarity of recorded music that we enjoy nowadays. Audio engineers and sound technicians can create alterations to the sound of instruments that were never possible before now too.

If there is too much resonance the audio engineer can remove it with a parametric equalizer. It can also reduce the volume or excessive boom of a double bass guitar for example. They are also useful when editing the extraneous noises or sounds. For example the sound technician can remove the sound of a guitar pic or the sound of a piano pedal that is squeaking during a recording. The equalizer will also provide feedback cancellation.

The parametric equalizer began to be used in the late 1990s as Digital Signal Processing (DSP) equipment. They later became available in the form of plug-ins for digital audio workstations. Now they are called digital parametric equalizers. Although this type of equalizer is considered to be the most powerful it is not without certain drawbacks. When a large amount of boost is used the cumulative noise can pose a problem. Once a sound is produced it is hard to repeat it exactly as well, since the controls are variable adjusted. Many recording studios still use a graphic equalizer along with a parametric equalizer.

Many people are using a parametric equalizer for their home audio or theater systems nowadays. You can find them for sale online or in your local audio or home theater retail stores. The Behringer Feedback Destroyer Pro DSP1124P is one that a lot of people are buying. The price tag on it is around $100. It is used for the subwoofer on your home theater system. This parametric equalizer was first developed for use in the entertainment industry and recording studios. You will be able to adjust he bandwidth as wide or as narrow as you want. You can enjoy the best sounds possible from your home theater system if you use a parametric equalizer to adjust your system so that it sounds the best for the room where it is in. If you want more control over the sound then you need a parametric equalizer because it will give you more detailed control and allow you to make finer tone adjustments that a graphic equalizer will.
