Most of what falls into this range is the upper overtones of bright instruments like cymbals and acoustic guitar, and some subtle ambience-a little boost up here can sometimes add a bit of openness, a.k.a. The highest frequency range (treble) is sometimes referred to as “air”. Accentuated frequencies in this range can help pull up a part in the mix, but too much can be harsh and peaky. The upper-midrange (Hi-Mids) is typically referred to as the “presence” range-with most instruments and voices the overtones here can bring the part forward in the mix, which is described as adding presence. This range is often attenuated (reduced in level) to prevent too much overlap of harmonics and overtones in a mix, which can negatively impact overall clarity. The area I labelled just “ Midrange” is the center couple of octaves of the audible range. The lower-midrange (Low-Mids) includes everything from upper bass-“punch”-to the frequencies that often account for a “boxy” quality, something usually avoided in a modern mix. The low frequency (bass) range up to around 200Hz or so contains the fundamentals (lowest frequencies) of instruments like kick drum and bass-this range usually affects the tonal quality that’s typically described as “thump” or “boom”, in studio jargon.

It can be useful to divide up the overall audible frequency range of 20Hz–20kHz into several frequency ranges, as a broad reference when addressing specific instruments or a full mix.
In this article we'll explore the typical frequency ranges that mixers turn to when dealing with some common EQ adjustments-I’ll assume familiarity with the basic layout and controls of a standard parametric EQ. But even while making adjustments by ear, it can help to have some idea of approximately where to start to address typical tonal issues on different tracks in a mix, and in the mix as a whole. Now, of course, that can be a good way to learn-to train your ears to recognize the tonal character of different frequency ranges, a skill that experienced recordists and mixers spend years building up. For those just getting started with the art of mixing, turning to EQ can feel like a writer staring with a blank page-there are so many options, but it’s often not clear what settings to make to accomplish what our ears are telling us needs to be done.Īside from the obvious-adjusting treble to affect brightness, adjusting bass to tweak the low end-deciding which frequencies to turn to and how much boost or cut to apply to deal with various tonal issues can often become an exercise in trial-and-error. EQ is, of course, one of the most-used processors in the studio.
