Abstract
An audio system and a method of using the audio system to determine an interaural head-related transfer function (HRTF) parameter, are described. The audio system can generate binaural recordings using microphones that are worn by a user in everyday scenarios. The audio system can measure interaural parameter values of selected segments of the recordings, and the measurements can be accumulated over time. The interaural HRTF parameter can be estimated based on the measurements. The interaural HRTF parameter can be used to adapt a generic HRTF to generate an individualized HRTF for the user. Other aspects are also described and claimed.
