12.12.2 EXPORT SET OF IMPULSE RESPONSES
If Impulse Response is selected only the last Truncation group is active.
The Output Folder define the path where the Impulse Responses in text format
will be saved. The file will be saved as Time Data impulse responses with the
naming convention requested by the EASE SpeakerLab:
IR <PHI*100> <THETA*100>.txt
If the Enable Truncation option is selected the time response is windowed with a
rectangular window with Time (ms) duration.
If the Truncate Text File option is selected the exported text files are limited to
the points inside the time window. This option reduce drastically the size of the
exported data sets.
12.13 H+V MODE
In this mode the 3D analysis module requires only 2 sets of polar measurements
with 5 degrees resolution: one for the horizontal plane and one for the vertical
plane.
This reduced data measurement set is then mathematically interpolated in order to
create the full sphere balloon.
The data set requested require the full horizontal polar from -180 to 180 degrees
and the vertical polar from -180 to 180 degrees.
The naming should look like:
<NAME> 0 <THETA*100>.MLS
for the horizontal polar and:
<NAME> 9000 <THETA*100>.MLS
for the vertical polar.
To collect the H+V data there are two possible approaches, using autosave in 1D
mode or 3D mode.
In case of the simpler 1D mode, when collecting the horizontal polar, the root
filename must include the ' 0' at its end. For the vertical polar the rootfile name
must include the ' 9000' at its end. The loudspeaker must be manually positioned in
horizontal and vertical positions.
If computer controlled turntables are available it is also possible to use the 3D
autosave mode. In this case it is necessary only to set the start, stop and step
values. Please use these settings:
Polar start -180: stop 180: step 5 degrees
Azimuth start 0; stop 90; step 90 degrees.
