Head Related Impulse Response Interpolation, Extrapolation and Personalization Using Deep Belief Networks

Tech ID: 30277 / UC Case 2019-256-0


In machine learning, a deep belief network is a generative graphical model, or alternatively a class of deep neural network, composed of multiple layers of latent variables, with connections between the layers but not between units within each layer.

Technology Description

Researchers from UC San Diego and an external collaborator have developed a machine learning algorithm for interpolation and extrapolation of head related transfer function (HRTF) databases. This invention provides for neural networks that can interpolate the HRTF at all locations around the head with reduced spectral distortion. The technology holds promise for predicting individualized HRTFs.


Any application which uses HRTF, such as augmented/virtual reality, games, music distribution, and music performances can benefit from this algorithm.
