The LAP Challenge aims at advancing personalized spatial audio technologies. It focuses on enhancing auditory localization and immersion in mixed realities through the personalization of Head-Related Transfer Functions (HRTFs).
Participants are encouraged to address one of the following:
- Task 1: Normalization of HRTFs for merging several datasets.
- Task 2: Spatial upsampling to achieve high-resolution HRTFs from minimal directional samples dataset.
- folder task1
task1_validate.mdemonstrates how to test deviations in terms of localization metrics predicted by an auditory model.task1_score.mdcontains the instructions to compute the overall score given the set of collections.
- folder task2
task2_metrics.ipynbshowcases how to use the SAM package to validate and compute the scores for Task 2.task2_create_sparse_hrtf.pycontains a function to create a sparse HRTF from a sofa file with a dense HRTF. It can be used to generate example sparse HRTFs for the challenge at different sparsity levels (number of positions). Requires sofar package.
