The 2024 Listener Acoustic Personalization Challenge

With enthusiasm, we announce the call for interest in the 1st Listener Acoustic Personalization Challenge (LAP 2024). The challenge acknowledges the diverse expertise within the signal processing community to facilitate cross-pollination of ideas and foster collaborative innovation in the audio domain, but not limited to.

Personalized Head-Related Transfer Functions (HRTFs) have been shown to enhance 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 endeavors to provide a platform where researchers can explore these challenges, advance state-of-the-art, and contribute to developing standardized metrics for personalized spatial audio. 

The 2024 inaugural edition will concentrate on two fundamental aspects of HRTF: spatial sampling and interpolation. Teams are challenged to submit solutions that address one or both tasks.

  • Task 1. HRTF harmonization and normalization for merging different HRTF datasets.
  • Task 2. HRTF spatial up-sampling for obtaining a high-spatial-resolution HRTF from a very low number of directions.

Grab your readers' attention with a strong opening line and explain why your offer is so great it's worth clicking the link below and/or filling out a form for.


If you are interested, sign up for updates!

Detailed descriptions and requirements for the task will be announced soon.
