IMEASY - Integrated Modular Expandable Audio Spatialisation sYstem Manual

The "Display View" window

The” Display View” window allows you to create a three-dimensional simulation of the ambience in which you actually perform Spatialisation. In the suggested virtual ambience, you must position the parallelepipeds in such a way that their coordinates, measured in metres, correspond to the position of the speakers you intend to use in the real space. The fields “H”, “D” and “W” in the area “Room Size” of the “Session Properties” window, allow you to set the value, in meters, of the side of the virtual cube inside which the Spatialisation will take place. The spheres in this window correspond to the available inputs. You will be able to move the spheres and listen to the resulting Spatialisation effect, or to design a trajectory for the selected sphere, and therefore for the selected input, using the following “tools”.

The Hand tool (Move Objects) allows you to change the virtual position in space of the selected object, input (with or without trajectory) or output. Select the object by double clicking on its name in the “Project Tree” window. Select it in the “Display View” window and keep the mouse button down while you move it. Release the button when you reach the desired position. Do the same to use the other two tools.

The Pencil tool (Draw Trajectory) allows you to draw a virtual trajectory in space for the selected input. Note that the temporal distance between nodes will be equal to the value preset in the Preferences, Tab General and “Step between nodes” field. A double click on the mouse with this tool in the View window “closes” the trajectory on itself, adding a last node coinciding, on the coordinates level, with the first one.

The tool Move (Move Node) allows you to change the virtual position in space of each single node of the selected trajectory. Note that you can use the combination of keys Command+arrow to the right or the left, to change the selection of the trajectory node to be moved. Once you have selected it, you will also be able to move the node using only the High, Low, Right and Left keys.

The other tools in the “Display View” window allow you to modify the three-dimensional visualisation of the ambience in which you will actually perform the Spatialisation.
The “Change View” tool is a pop-up menu that allows you to choose the point of view used in the “Display View” window (the position of your virtual camera, if you prefer cinematic terms). You will be able to visualise the scene from above (Top), frontally (Front), laterally (Side) or in perspective (3D). If you do not have a three- dimensional controller like TheBat or similar, and you only use your mouse, this tool allows you to modify the three-dimensional coordinates of the objects going from one combination of axes to the other. Top=XY, Front=XZ, Side=YZ.

The buttons “Stage Wireframe” and “Object Wireframe”, to the right of the Change View tool, allow you to use or not use the schematic representation of the objects contained in the scene

The buttons “Rotate, Translate and Restore View” allow you, respectively, to rotate, translate or centre the 3D visualisation. Select the desired tool, select any point inside the Display View window and move the mouse keeping the button down. The buttons X, Y and Z on the right allow you to limit the change to only one axis or to any of the possible combinations of axes.
The “Grid” and “Rotation” pop-up menus allow you, respectively, to change the resolution of the grid used in wireframe mode, and to slow down or speed up the rotation speed when you change visualisation using the Rotate mode.
Note that the joint use of the above options also allows you the visualisation and control

of trajectories including nodes outside the listening environment.
In this way you will be able to simulate the presence of audio sources coming from or placed outside the listening environment.
To move an object freely, remember to deselect the “Bound to Stage” check box corresponding to the input used, in the Input properties window or, as described later, in the “Object Inspector”.
