Three Fundamental Characteristics of An Equalizer (2)

 

Every instrument has its own "sound" called "tone" or "timbre". It can be thought of as the color of a sound. It is the energy arrangement of the harmonics of an instrument that give it its color and this is determined by how the instrument is designed and played. A trumpet sounding the note "A" sounds nothing like a guitar playing the same note at the same volume because their timbres (harmonics) and envelopes are different. An equalizer is a device that can alter the harmonic content and hence the tone or timbre of a sound.

 

 

There are many types of equalizer designs on the market. They range from simple cut and shelving filters (those familiar bass and treble tone controls found on inexpensive consumer electronics) to surgically precise multi-band processors costing many thousands of dollars found primarily in mastering facilities. 

 

The more control you have over the three EQ parameters (fc, gain, Q) the more complex but flexible the processor will be. Historically, all equalizers were analog circuits that were manually controlled by knobs, sliders and buttons. Being able to reset them from one project to the next was always a concern. Today, with many of the processors designed as virtual plug-ins for computer applications, not only are resetting issue a thing of the past, but dynamic parameter changes can be automated, allowing for an incredible degree of control and creativity.

 

Remember, any tool is only as powerful as its user. The true power of an EQ lies in your ability to hear frequencies, relationships, and tonal nuances within an instrument and a mix.
