<lom:description>
  
<lom:langstring xml:lang="en">In order to test the LISHPh MOBRIR rendering method open the MOBRIR_Rendering.pd File in puredata (http://puredata.info).
Make sure to obtain the zexy, iemlib, and bsaylor externals, install them and specify their paths
(e.g. by selecting &quot;help&quot; and &quot;find externals from the internet&quot; in puredata)

In the MOBRIR_Rendering patch you can listen to dynamic (variable-orientation) headphone rendering of a loudspeaker at 9m in front of the dummy head,  recorded in a reverberant staircase (RT=2.8s) in front of iem. BRIRs of the orientations 
-90°,-60°,-30°,0°,30°,60°,90° are real-time-convolved in Pd.
The Pd patch is wired to simulate a back-and-forth head rotation swiping from 90 to -90 and back, periodically.

The crossover of phase switching is set to fc = 2000Hz (Default) to listen to a properly adjusted  LISHPh method.
When setting it to fc = 20000Hz, you essentially get broadband linear interpolation. As audio example, you hear loopable segments of the piece &quot;What&#39;s trumps&quot; by Rhythmus-Sportgruppe,
