The audio examples on this site accompany the paper

They were created with the Chalmers Auralization Toolbox, which is available on GitHub: https://github.com/AppliedAcousticsChalmers/auralization-toolbox
All audio examples are binaural so that it is utterly important that you listen to them via headphones. We will shortly provide information on how we obtained the ground truth ear signals.
The following tables present audio examples for a volumetric sampling grid with 343 nodes.
With intermediate ambisonic representation (Fig. 4 in the paper):
| Room | Head orientation | Ground truth | Auralization |
| Small room | 0° | ||
| Small room | 45° | ||
| Small room | 90° | ||
| Large room | 0° | ||
| Large room | 45° | ||
| Large room | 90° |
Direct rendering (w/o intermediate ambisonic representation) (Fig. 6 in the paper):
