Source name Primary location channel Primary orientation channel Directivity Factor Name d = 0.000 Omni d = 0.500 Cardioid d = 0.625 Super Cardioid d = 0.750 Hyper Cardioid d = 1.000 Figure 8 or Dipole ↓ To remove a Source Object from the BinScape object list THE SIMULATION TOOLS Secondary location channel Secondary orientation channel Directivity factor Add sound object Cancel add object 2. Type a name for the Source Object in the Name box. 3. Set the Location Channel Number in the primary Location box. This Channel number specifies the channel on which the object will receive <strong>SNAP</strong> or Locator messages indicating its current (X,Y,Z) position. To ensure that the source can be moved independently of other sources this Channel Number should be unique. 4. Set the Secondary Location Channel Number if the source is to be moved relative to another object as described for the Listener object above. 5. Set the Angle Channel Number in the Primary Orientation channel box. This Angle Channel Number specifies the channel over which the orientation (facing) of the source is transmitted. 6. Set the Secondary Angle Channel Number if the source is to be rotated relative to another object. 7. Set the Dir Fact (Directivity Factor) of the Source Object. The Directivity Factor determines the shape of the sound field each source will produce. Some common directivity patterns are given below: 8. Click OK to add the Source Object to the BinScape object list. —or — Click Cancel to cancel the addition of the Source Object. From the main BinScape window 1. Select the Source Object to remove by clicking on the Source Object in the BinScape object list. 2. Click Delete. The Source Object will be removed from the BinScape object list.

Editing a BinScape Object ↓ To edit the details of Source Objects ↓ To reset the position of a Listener (receiver) or Source Object Room Switching ↓ To switch rooms Custom Room Filter Specifications THE SIMULATION TOOLS 1. Select the Source Object to edit from the BinScape object list. The source object will be highlighted. Click Edit. Alternatively, double-click the Source Object in the BinScape object list. 2. Edit Name, Location channels, Angle channels and Directivity Factors as required. 3. Click OK to accept the changes, or click Cancel to ignore the changes. 1. Select the Sound or Listener Object to edit by clicking on the Source Object in the BinScape object list. 2. Click Reset. The sound or Listener Object location will be set to the origin point at 0.00, 0.00, 0.00. BinScape allows the simulated room to be switched smoothly between three options representing spaces of varied acoustical damping and size properties. • Switch the current room filter using the Room listbox on the main dialog or by sending the <strong>SNAP</strong>SetRoom command while the Socket application is running. BinScape allows the user to load a new binaural room filter that replaces the first standard room filter set. The user can then switch between the remaining standard rooms (Two and Three) and the new Custom room. 1. Load a new binaural room filter set by selecting "Load Custom…" from the Room listbox and following the prompts to load the Left and Right filters. 2. The custom filter will replace Room One on the DSP. You can now switch between the Custom room and standard rooms Two and Three. 3. A valid custom Room filter set consists of two .sim files, each 6144 samples long, where the first sample of each filter occurs at t=384*Ts, Ts=sample period. Ie, you can make a valid Room filter file by taking a complete binaural room impulse response for each ear, discarding the first 384 samples and truncating the result at 6144 samples long.
