AniScape Commands Parameter Description c:\Huron32\AniScape\rooms\room.geo c:\Huron32\AniScape\rooms\roomx.sim c:\Huron32\AniScape\rooms\roomy.sim c:\Huron32\AniScape\rooms\roomz.sim OTHER SIMULATION TOOLS SNAPLoadRoom The Sound Field Filter can be loaded with a up to fifteen different room acoustic definitions. Each room is stored in a separate buffer. The data for the room acoustic definitions are stored in a number of binary data files on Huron, the set of data files for a room’s acoustics all have the same file name root but different extensions. The path passed in this command should be the full path of the data files without the file extension. For example, if the set of data files for a room resides in the following directory: The string passed would be c:\Huron32\AniScape\rooms\room in the path field of this command. This command returns a HuronAck packet to the remote computer. The cmd field of the HuronAck packet will contain HuronAniLoadRoom and the data field will contain the buffer number that the room acoustic files were loaded into. If the Sound Field Filter was unable to load the data files it will return -1 in the data field of the HuronAck packet. This buffer may also be used to switch between and clear rooms using the HuronAniSetRoom and HuronAniClearRoom commands. in const char* szPath The directory path of the data files SNAPSetRoom The Sound Field Filter can be loaded with a number of different room acoustic definitions. Each room is assigned a buffer number. This command can be used to switch the Sound Field Filter’s room acoustic definition buffer number. in long lBuffer The buffer number of the new room SNAPClearRoom The Sound Field Filter can be loaded with a number of different room acoustic definitions. Each room is assigned a buffer number. This command can be sent to remove the acoustics loaded in the defined buffer number. in long lBuffer The buffer number of the room to remove HURON TECHNICAL MANUAL PAGE 162
OTHER SIMULATION TOOLS SNAPGetRooms The Sound Field Filter application must be running in the VRack to receive a return from this command. out long *pnRooms Number of rooms loaded SNAPGetRoom It is important to send the command with the index field set the room you are interested in and the returned packet will contain the buffer and the path of the room. In order for this command to return the Sound Field Filter application must be running in the VRack. in long lIndex 0 based index of the room you want information on out char* szPath The directory path of the room’s data files SNAPSetMinDistance The Sound Field Filter has a setting called Minimum Source Distance which is measured in meters. This specifies a sphere around the listeners position with a radius of the minimum source distance value. If a sound object comes within this circle, its volume will remain fixed at the level on the edge of circle and its directionality will gradually turn to omnidirectional as it approaches the listeners position. The minimum source distance can be set using this command. in float fMSD The minimum source distance in meters SNAPGetMinDistance In order to receive a return from this command, the Sound Field Filter application must be running in the VRack. out float* pfMSD The minimum distance in meters SNAPSetDirFactor Each sound object in the Sound Field Filter can be assigned a direction factor, which is a floating point number between 0 and 1 which describes the radiation pattern for a sound object. Directivity Factor Description 0 Omni directional 0.5 Cardioid 1.0 Figure eight The source parameter identifies the Sound object and is equivalent to the primary location channel. Problems may arise if two sources sharing the same location channel have different directivity factors. Lake Technology recommends that sound objects with different directivity factors should always be assigned unique location channels. in long fSource The source. 0 is the receiver and the sound objects are numbered 1,2,3…etc in the order they appear in the Sound Field Filter in float fDirFactor The direction factor HURON TECHNICAL MANUAL PAGE 163
