HRTF personalization based on anthropometric features

A computer-implemented method, comprising:

• obtaining one or more training anthropometric feature parameters and corresponding Head-related Transfer Functions (HRTFs) of a plurality of training subjects;
• obtaining a test anthropometric feature parameter of a test subject;
• determining a sparse representation of the test anthropometric feature parameter of the test subject, the sparse representation representing the test anthropometric feature parameter of the test subject based at least on a subset of the one or more training anthropometric feature parameters belonging to the plurality of training subjects;
• applying the sparse representation to the HRTFs of the plurality of training subjects thereby modifying the HRTFs of the plurality of training subjects to obtain a set of personalized HRTFs for the test subject:
• and
• modifying at least one audio-signal based on the set of personalized HRTFs.

A system, comprising:

• processors;
• a memory that includes a computer-executable components that are executable by the processors to perform a plurality of actions, the plurality of actions comprising:
• obtaining one or more training anthropometric feature parameters and corresponding Head-related Transfer Functions (HRTFs) of a plurality of training subjects;
• obtaining a test anthropometric feature parameter of a test subject;
• determining a ridge regression representation of the test anthropometric feature parameter of the test subject, the ridge regression representation representing the test anthropometric feature of the test subject based at least on a subset of the one or more training anthropometric feature parameters belonging to the plurality of training subjects;
• applying the ridge regression representation to the HRTFs of the plurality of training subjects thereby modifying the HRTFs of the plurality of training subjects to obtain a set of personalized HRTFs for the test subject and
• modifying at least one audio-signal based on the set of personalized HRTFs.
