This blog entry will look into a mixing technique I discovered, called Scalar EQ-ing, which will improve tonal definition in your audio track!
"...boosting only frequencies within the key played in, using a very narrow Q setting, would only emphasize vital frequencies that are needed in the scale; making chords and melodies stick out [better] in any mix..."
(From my presentation write-up)
The image below shows the principle outcome of this technique in a frequency spectrogram:
"Ideally, this should be done spanning from 20-20,000 kHz which, without a plug-in that does it for you; would be very time consuming. However, only doing it over one octave already yields great results: better identification of individual notes in chords and a clearer overall sound. [...] In the audio examples below the range is of two octaves; starting from 440Hz and going up in an A-M scale to 1760Hz – a total of 16 frequency boosts."
This technique offers great clarity for any MELODIC instrument it's applied to. For example: when you have a dense and full mix consisting of drums, bass, left and right rhythm guitar, it may be hard to get a solo to shine through without bringing out too much harshness or other unwanted frequencies/noise/etc., especially in faster runs; so, Scalar EQ-ing can bring out the clarity by emphasizing vital frequencies in the scale of the solo.
The only problem being that if there is a key change in the song there would ideally be a plug-in that automates EQ settings, instead of having to manually set automation in the DAW. That sort of plug-in may be in the works for the future!!
Next are two sound samples which demonstrate Scalar EQ-ing. The first showing the raw input and then second example with the added EQ-ing technique:
