Master effects
Master effects influence the mixed sum of all audio tracks. For this purpose a
Master Audio Effects Rack and further plug-ins are installed in the Mixer
window. The MAGIX Mastering Suite (view page 185) is also available to help
produce perfect sound.
Sound optimization
This option opens an editor for correcting audio material discrepancies.
Select the cleaning function you desire from the upper part of the dialog:
 The equalizer (on page 178) allows you to manipulate the frequency spectrum
–
perfect for cleaning up muffled dialog.
 The compressor is a dynamic volume control that lends the overall sound a
deeper, richer quality.
 The stereo FX processor justifies the position of the sound in the stereo
panorama.
 DeNoiser, DeClipper, and DeHisser are professional noise reduction tools that
do exactly what their titles say they do.
Presets: You can try out the suitability of a number of presets in the preset
menu.
Temporarily deactivate all effects: Switches all the effects off.
Apply to all scenes: Applies the selected cleaning settings of all effects to
every scene of the movie.
Declipper
Should the input level of an audio recording be too high, overmodulation may
result at the louder parts (the signal peaks). This digital distortion is also called
"clipping": At the overmodulated area, the values that are too high are simply
cut off, and typical, quite unpleasant-sounding crackling and distortion appear.
MAGIX Video Pro X4 contains a special function for dealing with digital clipping
and analog distortions. Of course, this only works to a certain degree.
Using the fader you can set at what level the Declipper should register a signal
as being overmodulated and, if required, correct it (Clip level). This is
important, as different sound cards show different clipping methods. The more
the fader is turned up, the lower the level recognized by the program as
overmodulated. If the clip level is set too high, unwanted sound modification
may occur.
