Small Octave Range Example
In this example, assume that a bass drum in the sound track is very pronounced and the Audio EQ tool is used to deemphasize it. Also assume that there are voices on the same track as the music. The human voice covers a wide range of frequencies, and the challenge is to preserve the bass frequencies of the voices while deemphasizing the bass drum sound.
This example isolates the particular frequency that we want to deemphasize. In this example, we do not use the low shelf, but instead use the parametric midrange to isolate the frequency.
To isolate the frequency:
| 1. | |
Use the 1/4-octave influence range.
|
| 2. | |
Set the midrange EQ parameter to –15ádB.
|
| 3. | |
Use the EQ Range slider to move the midpoint of the parametric curve
until it isolates the bass frequency. In this case, the bass frequency that
we want to deemphasize is approximately 80áHz.
|
The following technique allows you to locate a specific frequency and
either emphasize or deemphasize it:
| – |
|
Use the 1/4-octave influence range and a large negative decibel
value.
|
| – |
|
Keep both the high shelf and low shelf set to zero.
|
| – |
|
Use the EQ Range slider to move the center point of the parametric
curve along the frequency range while you play the audio track.
|
Once you locate the frequency you want, you can adjust it as needed.
