Equalization Equalization (or EQ) is the process of adjusting (cutting or boosting) specific portions of the audio frequency spectrum within an audio signal. Equalization can help liven up a mix by adding punch to your bass tracks and by giving your leads and arpeggios an added crispness. Equalization can also be used to effectively remove unwanted frequencies to balance out a mix. To sum up, a good dose of EQ might be just what the doctor ordered when mixing a new track. Although reMix's EQ section is fairly basic, it will be helpful to take a quick look at the various types of equalization that exist: Shelving EQ is the most common of all EQs. It's found on radios, entry-level audio mixers, and, more importantly, in reMix. This type of EQ is comprised of two shelving filters, called the Low Pass Filter and the High Pass Filter. As you might guess, the Low Pass filter is responsible for either boosting or cutting the low end of the frequency spectrum, whereas the High Pass filter handles the high end of the spectrum, as shown in Figure 6.22. On certain hardware mixers that use Shelving EQs, you might find a Mid Pass Filter, which is responsible for cutting/boosting midrange frequencies and makes for a somewhat more accurate EQ section than the typical high-pass/low-pass setup. Graphic EQs are found in mid-level hardware mixers and in many pro audio software plug-ins. Graphic equalization incorporates a number of separate filters, each of which controls a specific slice of bandwidth within the frequency spectrum. These filters have controls (knobs or sliders) that can either boost or cut their assigned slice of bandwidth. Although they are a bit more complicated than Shelving EQs, the Graphic EQ (see Figure 6.23) is a step in the right direction toward accurately shaping your sound. Parametric EQs are the big daddy of equalizers, because they are the most accurate equalizers available. As opposed to Shelving and Graphic EQs, Parametric EQs allow you the flexibility of setting the center frequency, range, and the amplitude of each band. Parametric EQs are found within the virtual mixing consoles of most pro audio software, such as Cubase or SONAR (see Figure 6.24), and although they take a little more practice to understand, you can be sure to achieve much better results with them.
