Huron & SNAP Documentation

OTHER SIMULATION TOOLS
This command returns a HuronAck packet to the remote
computer. The cmd field of the HuronAck packet will contain
SNAPLoadRoom and the data field will contain the
buffernumber that the room acoustic files were loaded into. If
the Space Array 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 SNAPSetRoom and SNAPClearRoom commands.
in const char* szPath The directory path of the data files
SNAPSetRoom
The Space Array 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 Space Array’s room
acoustic definition buffer number.
SNAPSetRoom must be issued before loading a room into any
buffer but the default one (buffer 0).
in long lBuffer The buffer number of the new room
SNAPClearRoom
The Space Array 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
SNAPSetMinDistance
The Space Array has a setting called Minimum Source Distance
that is measured in meters. This specifies a sphere around the
listener’s 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 omni-directional as it
approaches the listener’s position. The minimum source
distance can be set using this command.
in float fMSD The minimum source distance in meters
