Each button marked by a number activates the group of parameters corresponding to the channel identified by the same number. A red LED visualizes the activated selection.







'Input/Output Channel Parameters' area

In this section of the main window, parameters change according to the channel number selected in the ‘Input/Output Channel Selection’ area. The features of the parameters however stay the same for each channel.







In this area, proceeding from left to right and from top to bottom, we find the following level or vectorial sliders:

‘Input Level’: regulates the input volume of the Spatializer for the selected channel.

‘Input LPF (Low Pass Filter) Cutoff’: sets the cut off frequency of the first-degree Low Pass filter for the selected channel. The default value is 127, no filter.

‘Gain Enhance’: increases or decreases the level of the spatialized signal for the selected channel within the area designated by the speakers. NB. If used only for some channels, it may modify the Spatialisation™ effect, sometimes with unlucky results. To be used sparingly. The value 64 corresponds to no set-up.

‘Sub Mix A Input Level’: sets the input volume for the Sub Mixer A marked by the same number as the selected channel.

‘Insert A Gain’: sets the input volume for the insert channel of group A marked by the same number as the selected channel.

‘Input HPF (High Pass Filter) Cutoff’: sets the first-degree high pass filter cutoff frequency for the selected channel. The default is equal to zero, or no filter.

‘Bell Factor’: it allows you to compensate for the speaker’s directionality for the output of the selected channel. NB. We advice values slightly above or below the default value 64.

‘SubMix B Input Level’: sets the input volume for the selected channel of the Sub Mixer B marked by the same number as the selected channel.

‘Insert B Gain’: sets the input volume for the channel inserting Group B marked by the same number as the selected channel.

‘Attenuation’: Regulates the percentage of level variation for the selected channel in relation to the distance of the source from the center of the virtual cube. Default value: 64.

‘Doppler Depth’: sets the depth of the Doppler effect for the selected channel. Default value: 0 (no effect), recommended value to obtain the most realistic result: 64.

‘Source Position Manager’: moving the red sphere with your mouse, you can set the position in the virtual space of the audio source entering the selected channel. The fields X and Y indicate the positions in relation to the center of the virtual cube, in meters. The field Z, modifiable through the fader above it, indicates the height of the source. NB. For example, in an environment with a height of 6 meters, the floor will be at -3 meters, since zero is set at the center of the virtual cube.

‘ITD (Interaural Timing Difference) Depth’: sets the depth of the ITD intervention for the selected channel. Default value: 0 (no effect). Recommended value: circa 64. NB. It’s advisable to use it only to position audio static sources and not for movement.

‘Front-Rear Spectral Enhance’: sets the depth of intervention of the filter dedicated to the simulation of the rear positioning of the source in relation to the center of the virtual cube for the selected channel NB. It’s advisable to use values only slightly above or below the default value of 64. Set the value to cancel the effect.

‘Speaker X (Y or Z) Position’: the three faders set the ns in meters of the speaker marked by the same number as the selected channel, in relation to the center of the virtual cube.
NB. For example, in an environment with a height of 6 meters, a speaker positioned at a height of 3 meters from the floor and at the exact center of the environment, will have the positions X=0, Y=0, Z=0, since the zero value is conventionally set at the center of the virtual cube.

The values of Speaker Position and of Source Position Manager vary according to the value of Room Side set in the Global Settings area; it is therefore advisable to set the latter parameter first of all. In order to fix the positions of the speakers at a predetermined position, even when the Room Side parameter varies, set the option ‘Lock Speakers’ in the A&G X-Spat menu.
