Audio system to determine spatial audio filter based on user-specific acoustic transfer function

An audio system and a method of using the audio system to determine one or more of a head-related transfer function (HRTF) or a headphone equalization (HpEQ) filter for a user, are described. The audio system can determine an acoustic transfer function that relates an output signal detected by a mic...

More Information
Summary:An audio system and a method of using the audio system to determine one or more of a head-related transfer function (HRTF) or a headphone equalization (HpEQ) filter for a user, are described. The audio system can determine an acoustic transfer function that relates an output signal detected by a microphone of a headphone worn by the user to an in input signal played by a speaker of the headphone. The acoustic transfer function corresponds to sound reflecting from a pinna of the user between the speaker and the microphone, and accordingly, the acoustic transfer function is user-specific. The user-specific acoustic transfer function can be used to determine the HRTF or the HpEQ filter for the user. Other aspects are also described and claimed.
