ABSTRACT
Equalizers are incredibly handy tools, both for fixing problems and for getting elements to come together nicely during a mix. Equalizers are precise tone controls, changing the timbre of a sound by making one part of the spectrum louder or another softer. But they didn't start out that way. Matching equalizers can be useful, but they're not magic. The sounds users are matching must have similar spectral patterns before any equalization; otherwise, the automatic circuits will try to compensate for the wrong thing. The point of an equalizer is to raise or lower the volume in a specific frequency band, without affecting other frequencies. Tuning a shelving equalizer takes a little more care since the controls can seem interactive. Because of its gentle slope, a large boost at a high frequency might sound like a smaller boost at a lower one, but it's probably adding more noise.
