EFFECTS MENU 539
The human ear is generally incapable of perceiving frequencies below 300 Hz. Stereo
effects in the bass range can be disruptive as different delays can often result in obliteration
which becomes noticeable in spongy and squishy playback of the basses.
The treble range may be important for directional hearing, however, spreading of the base
width often causes annoying side effects here.
Due to these reasons, the base width is usually enlarged or the direction of a mono source
is changed in a middle band.
In the bass area the base width is set to mono by default. Enlarging the base width only
makes sense for special applications.
The treble band is retained during the following standard application and is not changed.
Enlarging the stereo base width
For this task you should set the basic width controller of the middle band to a higher value
(between 101 and 200).
More powerful bass by reducing the base width in the bass range
Set the base width controller of the bass band to mono. The setting of the lower separation
frequency is also significant for this task. Typical settings for this application are between
300 and 600 Hz. If the separation frequencies are higher, narrowing of the stereograph is
already audible depending on the properties of the audio material.
Verification and correction of a completed mix in the stereograph.
If you wish to check and perhaps correct the base width and the panorama setting in
various frequency ranges, you can take care of this task in all three bands as follows:
1. Activate "Solo" mode.
2. Open the phase correlator during real-time preview.
3. The base width can be estimated according to the amplitude of the display. The
horizontal amplitude increases in relation to the vertical amplitude as the base width
increases. The panorama setting can be verified by the gradient of the display. The display
tilts to the side of the stereo channel with the higher level.
4. If necessary you can now correct each channel with the panorama and base width
controllers.
Move a mono source in the panorama (mix direction)
The first step is to "filter out" the mono source (for example, vocals) so that the remaining
part of the mix remains unaffected.
