Putting it all together with multiband EQ

Now that we understand the different types of filters commonly found in both hardware and software equalizers, it's worth mentioning that many EQs will incorporate multiple filter types into a single processor. This is often referred to as a multiband EQ. Multiband EQs generally feature one or more parametric bands in addition to high- and low-shelving filters and high- and low-pass filters at each end of the frequency spectrum. Many multiband EQs will also feature input and output gain controls that can be used to raise or lower the entire level of the signal. They usually have a phase or polarity invert button also. The phase flip switch allows you to invert the waveform's amplitude, swapping the pushes for pulls and the pulls for pushes shown here in the graph. This switch is often used to compensate for phase offsets created in multi-mic recording scenarios. For instance, if you mic a snare drum with a mic on the top head and the bottom head, those two signals might not reach the…
