A benchmarking campaign on acoustic and non-acoustic factors in immersive technologies.
Personalized Head-Related Transfer Functions (HRTFs) have shown promise in enhancing auditory localization and immersion in mixed realities. However, relevant issues such as the accurate acquisition of user-specific anatomical data, efficient simulation algorithms, and effective user validation do not converge into a common and internationally recognized benchmark for evaluating HRTFs.
The LAP Challenge endeavours to provide a platform where researchers can explore these challenges, advance the state of the art, and contribute to the development of standardized metrics for personalised spatial audio.
The inaugural edition of the challenge will concentrate on two fundamental aspects of HRTF: spatial sampling and interpolation. Teams are challenged to submit their solutions that address one of two tasks:
The documents below outline the complete description for each task.
The evaluation code is also publicly available here:

The challenge will have an award ceremony hosted by the premier European conference on signal processing: the 32nd European Signal Processing Conference, EUSIPCO 2024, to be held in Lyon, France, on August 29th, 2024. The results will be presented in a 2-hour workshop.
The tentative program includes:
Top-ranked solutions will be invited to submit a paper describing their method and result to be published in the IEEE Open Journal of Signal Processing (OJ-SP), a fully open-access publication of the IEEE Signal Processing Society, with a scope encompassing the full range of technical activities of the Society. Article processing charge (APC) waivers will be also available upon request.
Since the challenge provides original data and evaluation processes, participants also have the flexibility to submit already published solutions.
Winners of the two tasks will be invited to participate and reimbursed for the registration fee to EUSIPCO24 and, until available funds are reached, for travel and accommodation.
