1. A method, comprising:
generating an HRTF calculation system taking anthropometric measurements and, optionally, demographic data of a user as input and returning a personalized HRTF for the user as output,
obtaining 3D scans of a plurality of training subjects,
generating HRTFs for the plurality of training subjects by performing acoustic scattering calculations on anatomical characteristics captured in the 3D scans,
collecting anthropometric measurements and, optionally, demographic data of the plurality of training subjects, and
training the HRTF calculation system to transform the anthropometric measurements and, optionally, demographic data of the plurality of training subjects to the HRTFs.
