摘要： A method of enhancing vertical polar localization of a head related transfer (HRTF). The method includes splitting an audio signal and generating left and right output signals by determining a log lateral component of the respective frequency-dependent audio gain that is equal to a median log frequency-dependent audio gain for all audio signals of that channel having a desired perceived source location. A vertical magnitude of the respective audio signal is enhanced by determining a log vertical component of the respective frequency-dependent audio gain that is equal to a product of a first enhancement factor and a different between the respective frequency-dependent audio gain at the desired perceived source location and the lateral magnitude of respective audio signal. The output signals are time delayed according to an interaural time.
