APPLICATION
Creating your own original sound
Both
instruments
and
voices
have
their
own
frequency bands, as shown in the figure.
By sliding the graphic equalizer's controls up and
down, the volume of the desired instrument can be
increased or reduced.
For instance, if the 60Hz control is slid upward, the
bass drum takes on a more dynamic sound while
sliding the 1kHz contro!
upward
positions the
person(s) singing in front. Sliding the 6kHz contro!
upward makes the cymbal and "high hat'' sound
even clearer.
In addition,
instruments
and
voices
contain
a
great
many
harmonic
components
besides
the
fundamental
frequency
band
and
so
you
can
easily have a lot of fun creating your own sound
by manipulating the seven controls.
