1. An audio personalisation method for a first user, comprising the steps of:
testing the first user on a calibration test, the calibration test comprising:
requiring a tested individual to match a test sound to a test location, either by controlling a position of the test sound or controlling the position of the test location, for a sequence of test matches,
each test sound being presented at a specified position using a default head related transfer function ‘HRTF’,
receiving an estimate of each matching location from the first user, and
calculating a respective error for each estimate, to generate a sequence of location estimate errors for the first user; and
comparing at least some of the location estimate errors for the first user with estimate errors of the same locations previously generated for at least a subset of a corpus of reference individuals;
identifying a reference individual with the closest match of compared location estimation errors to those of the first user; and
using an HRTF, previously obtained for the identified reference individual, for the first user.
