Abstract: A system for generating a transfer function indicating audio transmission characteristics of an input device associated with a processing device includes: a parameter determining unit configured to determine one or more parameters of the input device, where the parameters include a location of a microphone associated with the input device and a location of one or more respective input and/or output elements associated with the input device, an audio characteristic determining unit configured to determine one or more characteristics of audio transmission between respective input and/or output elements and the microphone, where the characteristics include one or more of an attenuation, resonance, and/or change in frequency profile of audio associated with the respective input and/or output element, and a transfer function generating unit configured to generate a transfer function in dependence upon the determined audio characteristics.

Abstract: An audio personalisation method for a first user includes: testing a first user on a calibration test, the calibration test comprising requiring a user to match a test sound to a test location, either by controlling the position of the presented sound or controlling the position of the presented location, for a sequence of test matches, each test sound being presented at a 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.
