This database entry contains stimuli and results from the follow up experiment to [1, 2]. In the experiment different Wave Field Synthesis (WFS) systems synthesising a point source were rated in terms of their perceived coloration compared to a real point source. This was done for different audio material, namely pink noise, speech, and music and different listener positions. The different WFS systems consisted of a circular loudspeaker array with a radius of 3m and a linear loudspeaker array with a length of 3m, but different number of employed loudspeakers. To control for the exact listening position, allow instantaneous switching between listening positions, and allow for very high numbers of loudspeakers in the WFS systems the experiment was performed with binaural synthesis without head tracking.

The corresponding binaural room scanning (BRS) files for the binaural simulation can be found in the file `brs.zip`, the employed noise and speech stimuli in `stimuli.zip` (note that we cannot release the employed music stimulus, which was a twelve second clip from the electronic song “Luv deluxe” by “Cinnamon Chasers”). The file `results.zip` contains the results of all 16 listeners and the file  analysis.zip` calculated average values and a plotting script.
