This picture shows the right side; you can manage all the X-Spat parameters that should be modified in real time, independently for each audio channel or couple of channels. Select the mono or stereo channel for which you want to set the input and output parameters using the 'Channel(s)' menu.
'Input Level': regulates the input volume of the Spatializer for the selected channel.
'Bell Factor': it allows you to compensate for the speaker's directionality for the output. '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.
'HPF / LPF Cutoff': sets the first-degree high/low pass filter cutoff frequency.
'Doppler Depth': sets the depth of the Doppler effect for the selected channel.
'Sub Mix A/B Input Level': sets the input volume for the Sub Mixer A/B marked by the same num- ber as the selected channel.
'ITD (Interaural Timing Difference) Depth': sets the depth of the ITD intervention for the selected channel.
'Front-Rear Spectral Enhance': sets the depth of intervention of the filter dedicated to the simulation of the rear positioning of the source.
'Insert A/B Gain': sets the input volume for the insert channel of group A/B marked by the same number as the selected channel.
'Gain Enhance': increases or decreases the level of the spatialized signal for the selected channel within the area designated by the speakers.

If you press Shift+Ctrl+M all the values will be visualized in MIDI or specific measure unit (such as meter, frequences Hz, dB and so on).
