4D MONITOR

 4D Monitor

The 4D Monitor visualises the virtual sound sources and other spatial data. It is a passive application that provides several tools to retrieve detailed information in order to keep track of the spatialisation. The source colors and names are set externally (e.g. in Ableton Live).

On the bottom left you can switch between the perspectives Front, back, side, top and 3D. With the arrow keys you can rotate the camera around the center and freely set e perspective, and with + and - you can zoom in and out.

In the menu above you find from left to right values, source select and options.

This provides an overview of detailed spatial data for both Global and Source parameters. Most of the times the 3D visualisation is sufficient for monitoring purposes, however, when for example more interfaces run next to each other (e.g. 4D M4L and 4D PAD) then this detailed overview can give insight into what data is actually active. Another function is to see the result of a series of offsets. For instance, 4D M4L let's you set several position offsets (incl. global) and the resulting final position is only known within the Engine. This overview shows you the result of the offsets combined.

The selected source shows a white frame around the object. Its data will be shown in the Values section and also its position and dimensions are displayed at the bottom right.

Selecting a source channel in Ableton Live and in 4D Pad control this remotely.

Night mode: Enable night mode to have a dark image of the spatialisation.
Follow selected source: Enable this to make the camera follow the selected source.
Show spatial delays: (Enabled by default) In case of complex spatialisations with a large amount of sources it could be useful to disable the Spatial Delay visualisation to create a clearer overview.
Show paths: (Enabled by default) Same as with Spatial Delays, excluding paths in the visualisations may provide a clearer overview.
Show grid: (Enabled by default) Enable/disable the visualisation of speakers and columns.
Show columns: (Enabled by default) Enable/disable the visualisation of columns.
Display amplitudes: (Enabled by default) Enable/disable the amplitude visualisation of the selected source; the speakers lighting up according to their panning amplitudes, in the same color as the source.
Show speaker properties: Enable/disable panning values of the selected source.
Show source data: Enable/disable the position and dimensions data of the selected source on the bottom left corner.
Show axes helpers: Enable/disable the indicators of the horizontal axes (X and Z) and their positive and negative directions. This is to help with the orientation within the cartesian space.
Sources enable matrix: Display/hide a series of toggles to show/hide individual sources. Visualising only a selection of sources could help gaining overview of the spatialisation.
