Using EQ Página 1 de 8

Paul White and Mike Senior explain how to get the best practical results from
equalisation by understanding the true frequency ranges of most instruments and
voices.
An understanding of the variety of different equalisation tools
at your disposal can help in choosing the most suitable type
of processing for any situation. However, using equalisation
is about much more than just selecting the correct unit and
this month, we will be looking at how best to employ
equalisation techniques in music production.
The first challenge when equalising musical sounds is in
deciding which area of the frequency spectrum corresponds
to which element of a sound's timbre. If you're wanting to
emphasise the click of a bass drum, where should you
boost? Alternatively, if your guitar sounds boxy, where can you cut most effectively?
Pitch & Frequency
One thing that can help a little in deciding this is to know what frequencies correspond to
the fundamentals of each musical pitch. For a start, this allows you to define the lower limit
of the range of frequencies generated by pitched sounds. Figure 1 shows how the pitch
ranges of mon instruments, and hence how the ranges of their fundamentals,
relate to frequency. You can see from this that you're not likely to get much in the way of
useful tonal change if you try to EQ
