Join Brian Lee White for an in-depth discussion in this video Putting it all together with multiband EQ, part of Audio Foundations: EQ and Filters.
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 listener at the same time…
