Colouration in Local Wave Field Synthesis - Data
<p>This data set contains stimuli and results from two experiments for human perception of colouration in Stereophonics, Wave Field Synthesis (WFS), Near-Field-Compensated Higher-Order Ambisonics (NFC-HOA), Local Wave Field Synthesis using Spatial Bandwidth Limitation , and Local Wave Field Synthesis (LWFS-SBL) using Virtual Secondary Source (LWFS-VSS) simulated via binaural synthesis using head related impulse responses (HRIRs). The data for the two experiments is stored separately in `exp1.zip` and `exp2.zip`. Both files have the same structure: The corresponding binaural room scanning (BRS) files for the binaural simulation can be found in the directory `brs`. The employed stimuli is contained in `stimuli`. The Multiple Stimulus with Hidden Reference and Anchor (MUSHRA) ratings are stored in `results`. The `analysis` directory includes MATLAB/Octave scripts for the statistical evaluation in the publication. The main script is `analyse_results.m`. The source code is licensed under GPL v3.</p> <p>Abstract of the Publication:</p> <p>Sound Field Synthesis techniques including Wave Field Synthesis and Near-Field-Compensated Higher Order Ambisonics aim at a physically accurate reproduction of a desired sound field inside an extended listening area. This area is surrounded by loudspeakers individually driven by their respective driving signals. The latter have to be chosen such that the superposition of all emitted sound fields coincides with the desired one. Due to practical limitations, artefacts impair the synthesis accuracy resulting in a perceivable change in timbre. Recently, two approaches to so-called Local Wave Field Synthesis were published which enhance the reproduction accuracy in a limited region while allowing stronger artefacts outside. This work reports on two listening experiments comparing conventional techniques for Sound Field Synthesis with the mentioned approaches. Furthermore, the influence of different parametrisations for Local Wave Field Synthesis is investigated. The results show that the enhanced reproduction accuracy in Local Wave Field Synthesis leads to a reduction of perceived colouration, if a suitable parametrisation is chosen.</p>
COLOURATION IN 2.5D LOCAL WAVE FIELD SYNTHESIS USING SPATIAL BANDWIDTH-LIMITATION -- Data
<p>This data set contains stimuli and results from an experiment for human perception of colouration in Stereophonics, Wave Field Synthesis, Near-Field-Compensated Higher-Order Ambisonics and Local Wave Field Synthesis simulated via binaural synthesis using head related impulse responses (HRIRs). The corresponding binaural room scanning (BRS) files for the binaural simulation can be found in the directory `brs`. The employed stimuli is contained in `stimuli`. The Multiple Stimulus with Hidden Reference and Anchor (MUSHRA) ratings are stored in `results` together with a text file to describe the content in more detail. The `analysis` directory includes scripts for the statistical evaluation in the publication. The source code is licensed under GPL v3.</p> <p>Abstract of the Publication:</p> <p>Sound Field Synthesis techniques, such as Wave Field Synthesis aim at a physically accurate reproduction of a desired sound field inside an extended listening area. This area is surrounded by loudspeakers individually driven by their respective driving signals. Due to practical limitations, artefacts impair the synthesis accuracy resulting in a perceivable change in timbre compared to the desired sound field. Recently, an approach for so-called Local Wave Field Synthesis was published which enhances the reproduction accuracy in a limited region by applying a spatial bandwidth limitation in the circular/spherical harmonics domain to the desired sound field. This paper reports on a listening experiment comparing conventional Sound Field Synthesis techniques with the mentioned approach. Also the influence of the different parametrisations for Local Wave Field Synthesis is investigated. The results show that the enhanced reproduction accuracy in Local Wave Field Synthesis leads to an improvement with regard to the perceived colouration.</p>
