This post contains supplementary audio examples for the paper:
Geier, Wierstorf, Ahrens, Wechsung, Raake, Spors: Perceptual Evaluation of Focused Sources in Wave Field Synthesis. 128th AES Convention, London, May 2010.
Please use headphones to appreciate the spatial information!
The provided files are named using the following scheme:
<array length>_<radius>_<angle>_<input sound>.wav
Array length is 4 meters or 10 meters; the radius (= distance from the focused source) is 1 and 4 meters, respectively. The focused source is always located one meter in front of the loudspeaker array. The angle is 0, 30 or 60 degrees. The input sound is either castanets or female speech.
The geometry of the experiment is shown in the following figure.
In addition, there are also 2 reference stimuli, ref_phi0_speech.wav and ref_phi0_castanets.wav using plain HRTFs for the frontal direction.
