Abstract
A method, apparatus, and manufacture for audio transmission is provided. A head-related transfer function (HRTF) profile most accurate for a user is selected from several HRTF profiles. The HFTF is selected by: wirelessly transmitting test signals to binaural headphones, then receiving feedback from the user, and then selecting the HRTF profile based on the feedback. Subsequently, the selected HRTF profile is employed to convert a multi-channel audio signal into a stereo signal such that the stereo signal retains the immersive and spatial audio characteristics of the multi-channel audio signal. Next, the stereo signal is wirelessly transmitted to the binaural headphones.
