Join Brian Lee White for an in-depth discussion in this video Using graphic EQ, part of Audio Foundations: EQ and Filters.
A graphic EQ is a special type of EQ that has fixed frequency and Q values…and is arranged in a multi-band, almost mixer-like presentation.…The only control in a graphic EQ is gain, which can either be boosted or cut to…alter the amplitude of a fixed-frequency spectrum.…Graphic EQs offer a fixed number of frequency points, or bands, that can be altered.…This simplicity, along with the inherent visual presentation of the total EQ…curve, makes them very simple to use and especially effective at certain tasks.…
Because they can contain many unique bands, sometimes over 30, graphic EQs are a…popular choice for calibrating playback systems to a specific room or space.…They are often used to compensate for a venue's acoustics in live sound systems…and can also be found performing the same task in many recording studios.…A large number of unique bands can help an engineer neutralize very specific…room modes or points of resonance in a space.…Sometimes I like to use graphic EQs for normal everyday EQ, tasks such as EQing a…
