Do your recordings lack definition? Are the drums hard to hear with everything else playing? Is your mix a giant mess? Are you feeling depressed?

Well, I may have an answer to help all of the above (except the last one). First, let me ask you: do you use your high-end frequencies (10 k – 20 kHz)? If not – you definitely want to pay attention. If you do – you can add your comments and help the poor sods I mentioned in the previous sentence.

The average person’s hearing ranges from 20 – 20000 Hz. So, when you see the faders on your EQ going up to 20 kHz – don’t ignore the last ones! This is why: the frequencies above 10 kHz give definition and add a much needed ‘sparkle’ to certain instruments. Also, if you use the whole frequency spectrum, you can create a feeling of space or bunching. Another way of doing this is by using panning, but these two techniques should be used hand-in-hand. For further information on panning see my post: Panning for Gold.

Cymbals’ frequencies are typically between 2 k and 20 kHz. Thus, if your drum track has the highs cutoff, they will lack definition and will not stand out. Other instruments which require a ‘sparkle’ factor are acoustic guitars, pianos and vocals. Vocals sound best when boosted in the low-frequencies (100 – 200 Hz) and high-frequencies (10 k – 20 kHz). Boosting the mid-frequencies (800 – 5000 Hz) can actually make the vocals more muddy and this is a common mistake.

To conclude: we have learned that the high-frequencies are important – don’t forget them or reduce them on your EQ. It is for this very reason that condenser mics are better than dynamic ones. Condenser microphones have a better high-end response and thus have more DEFINITION.
