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 SNAPSetRoom 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.
