An Individualized HRTF Model Based on Random Forest and Anthropometric Parameters
International Conference on Intelligent Human-Machine Systems and Cybernetics, 2023Individualized head-related transfer functions (HRTFs) can improve the auditory performance of the listener in the virtual acoustic environment. This study introduced random forest to fit the complex relationship between anthropometric parameters and ...

Implicit HRTF Modeling Using Temporal Convolutional Networks
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2021Estimation of accurate head-related transfer functions (HRTFs) is crucial to achieve realistic binaural acoustic experiences. HRTFs depend on source/listener locations and are therefore expensive and cumbersome to measure; traditional approaches require ...

Proceedings of the 2008 International Conference on Advances in Computer Entertainment Technology, 2008
Dimensionality reduction is a statistical tool commonly used to map high-dimensional data into lower a dimensionality. The transformed data is typically more suitable for regression analysis or classification than the original data. Being of high dimensionality, HRTF data is commonly reduced using Principal Components Analysis (PCA).

P-HRTF: Efficient personalized HRTF computation for high-fidelity spatial sound
2014 IEEE International Symposium on Mixed and Augmented Reality (ISMAR), 2014Accurate rendering of 3D spatial audio for interactive virtual auditory displays requires the use of personalized head-related transfer functions (HRTFs). We present a new approach to compute personalized HRTFs for any individual using a method that combines state-of-the-art image-based 3D modeling with an efficient numerical simulation pipeline.

Towards HRTF Personalization using Denoising Diffusion Models
IEEE International Conference on Acoustics, Speech, and Signal ProcessingHead-Related Transfer Functions (HRTFs) have fundamental applications for realistic rendering in immersive audio scenarios. However, they are strongly subject-dependent as they vary considerably depending on the shape of the ears, head and torso.

Personalized HRTF Modeling Using DNN-Augmented BEM
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2021Accurate modeling of personalized head-related transfer functions (HRTFs) is difficult but critical for applications requiring spatial audio. However, this remains challenging as experimental measurements require specialized equipment, numerical ...

Alternatives to HRTF measurement
2012 35th International Conference on Telecommunications and Signal Processing (TSP), 2012This paper compares methods to acquire the HRTF (Head Related Transfer Function) applicable to navigation purposes, especially for the visually impaired. The most frequently used method for the HRTF acquisition (in general case) is the direct measurement of the HRTF. However, this method is very time-demanding.

HRTF Recommendation Based on the Predicted Binaural Colouration Model
IEEE International Conference on Acoustics, Speech, and Signal ProcessingOver the past few decades, several databases of head-related transfer functions (HRTFs) have been recorded using both mannequin heads and individual subjects. Some of these databases also include the measurements of the subjects’ anthropometric features (
