Audio Equalizer

An audio equalizer, also known as a graphic equalizer, is a set of sliders that allows the stereo user to increase or reduce bands of sound that are on frequencies. The result is a more focused sound, with bass and treble specifications to suit the individual listener. The name from graphic equalizer comes from the fact that we can see the audio levels as we are adjusting them. A typical audio equalizer includes a series of filters and amplifiers that are each set to a certain frequency. A typical audio equalizer will have two sets of these levels, one for each channel in the stereo system. Gain controls affect volume, and are typically represented by a button that you slide up or down. Audio equalizers are most frequent in medium- to high-grade stereo systems, and every recording studio worth its salt will have one. You can even find equalizers for your computer sound, or for your car stereo.

Different kinds of media sound differently on various graphic equalizers. For example, a particular device may play music files better than audio on feature films. In addition, be sure to find an audio equalizer that that doesn’t fuzz up or distort the sound, which is a common problem among audio equalizers. Audio equalizers are great for people with an extensive music collection that includes older recordings, such as cassettes and older CDs. Graphic equalizers brighten up the sound.

Another thing to consider when purchasing a graphic equalizer are “sticky buttons,” or buttons or slides that do not move as easily or as intuitively as you would like them to. Sticky buttons can result in the cutting out of sound on certain frequencies, negatively affecting the quality of sound. In addition, once you find the perfect balance among dials and switches, some models do not contain hash marks that allow you to easily remember these things. This can be easily remedied by applying magic marker to the places that you would like to remember.

Below are some examples of top equalizers in the market.
