Another application of this technique is in de-essing. When de-essing, you want
sibilants in a voice to be heavily compressed. To achieve this, set a high level of
compression, but use the filters to remove frequencies that are not affected by
sibilance (as a starting point, set the low filter at 2kHz and the high filter at 10kHz,
and adjust accordingly). This causes only the sibilants to be heavily compressed.
Note that, because of the range of the filters, it is possible to set them so that there is
no compression at all. Since only the frequencies between the two filter settings are
compressed, be careful not to set the frequency of the high filter below that of the low
filter: if you do, no frequencies reach the compressor side chain, so no compression is
applied to the signal.

When to use Equalisation
You can apply equalisation when recording or while mixing down a finished track. You
usually record flat (without equalisation) and then apply equalisation at mixdown,
unless you are assigning several instruments to a single track, in which case you need
to get the equalisation correct during recording.
