MAPP Online Revision History

18 July 2003 v1.3.004j This version adds support for a single horizontal M3D-Sub, and the help files have been updated to address the "approximate distance" issue with subwoofers.

11 July 2003 v1.3.004i The MILO loudspeaker and MILO Array Wizard have been added in this version. The M3D-Sub Cardioid subwoofer is now modeled, and the M3D cardioid pattern is also now modeled (previously the cardioid nature of the M3D was not visible because sound field predictions were not allowed below 125Hz). Low frequency sound field predictions are now available from 32Hz; previously the lowest allowed was 125Hz. The M3D array wizard now includes M3D-Sub.

19 February 2003 v1.3.004 Virtual SIM split off into its own window with its own menu bar. MM4 and MTS4A loudspeakers added. Full-space SB2 loudspeaker data added (was half-space). Help files rearranged, updated, and extended. Save as Webpage improved. Escape key now exits all dialogs except file and help (which are provided by Java). Configure Walls now updates the room size on the screen whenever focus moves away from one of the dimension text fields. Printing no longer freezes the app while it queues.

30 October 2002 v1.2.129 Arbitrary Zoom functionality added. Mouse behavior enhanced to model typical multi-modal operation using keyboard shortcut modifiers. Additional accelerators (keyboard shortcuts) added to the menus.

7 October 2002 v1.2.101 M1D and M1D-Sub added. A weighted SPL is now calculated. Linear Frequency weighted Total SPL is only shown when data extends below 100 Hz (i.e., M1D and M2D). Impulse Response is no longer peak-hold-downsampled. Every point is shown. Clicking and dragging the mouse now displays the time with two digits of precision (although the peak impulse time in the table still has slightly more precision). Center Frequency drop box in the Sound Field toolbar. Numbers now have a nicer, locale sensitive, format. That is, they include commas and periods "1,234.56" or "1 234,56" as is appropriate for your country. File dialogs now default to the directory of the last successful file operation.

8 July 2002 v1.2.30 Save as Web Page now generates an html document with images of Sound Field, all Virtual SIM Panels, and the loudspeaker and room configuration data. Right-click context popup menus added. Right Click Configure places the Loudspeaker, Microphone, or Architectural Visual Aid at the current mouse position. Click and drag in Virtual SIM displays the fequency/dB at that location. Configure | Image Preferences lets you choose the number of colors in a sound field prediction. Export Sound Field Image exports the Sound Field image without gridlines, colorbar, etc so that it can be imported into AutoCAD. Minimum room size reduced to 3 meters square. Angle change is now reported during rotate. Export frequency and impulse data as a csv file. Configure | Microphone from the main menu now defaults to the center of the room.

9 May 2002 v1.1.11 Added load/save of system design. "Save as Array" enabled in Configure | Loudspeaker Array. Virtual SIM plots improved.

2 April 2002 v1.0.45 Added Frequency Response Smoothing in Virtual SIM, HTML help files, and SB2 Loudspeaker Model.

20 March 2002 v1.0.25 M2DSub added. Help | Online documents option added. Added labels in Virtual SIM panels that report Natural Environment/Air Attenuation variables. Compute | Virtual SIM is automatically turned on when you add a microphone, and turned off when you delete the last microphone. Predict automatically selects the microphone if there is only one.

12 March 2002 v1.0.5 Added VX-1. Walls are displayed in sound field. Approximate distance from microphone to loudspeakers is reported in Virtual SIM.

1 March 2002 v1.0.0 Added Loudspeaker Array Wizard, M2D and low frequency support, short-cut keys. Increased size of prediction plane. Renamed menus: select to edit, display to view. Added tools menu, added "select all", delete and deselect are no longer object specific. Predict all loudspeakers if none selected.

25 January 2002 Added support for drag and drop, rotate, and Architectural Visual Aids.

17 October 2001 Added Walls, Virtual SIM, Calibrated SPL, Normalized Sound Field Plots.
