Surround Balance
[0.00 … 1.00]
Mono
defines the amount of direct sound mixed into the surround
channels.
0.0 provides pure ambient sound while 0.1 to 1.0 will increase the
amount of direct sound. Works only if upmix mode is set to mono or
switched to mono in auto mode. For auto mode lower values (0.2 –
0.4) are recommended to prevent unwanted effects when auto
switching between Mono and Stereo.
LFE Enable
[OFF / ON / Effect Gate]
You may turn this option on if the upmix process is to generate a
subwoofer signal that will appear in the LFE channel. When using
the Effect Gate function the system interactively processes the
subwoofer signal and generates a signal that comes very close to a
real LFE signal, without creating permanent rumble and bass
excitation.
LFE Cutoff Freq (Hz)
[60, 80, 100, 120]
sets the cutoff frequency for the generated LFE signal.
LFE Gain (dB)
[-20.0 … 20.0]
You can set the LFE level here
LFE Effect Gate
[-20.0 … 0.0]
Threshold (dB)
sets the relative threshold of the Effect Gate processor.
Important Note! If you encode the surround signals from this upmix to a Dolby format we recommend
to set the center and the surround downmix level to -3dB for best downmix compatibility.
Metering
If you click on the Metering icon on the left hand side in the
status window, a Java applet opens up. This feature is only
available if a valid Java plug-in is available for the browser that is
used to display the GUI.
