MULTI-DIMENSIONAL PARAMETRIC AUDIO SYSTEM AND METHOD
摘要
<p>Systems and methods that use ultrasonic emitters for producing multi-dimensional parametric audio are provided. The systems and methods can be configured to determine HRTF filters for the left and right ears of a listener using an optical imaging system to scan a profile of a listener. Audio content may be encoded into a left and right channel for producing a three dimensional sound effect for the listener of the audio content by: processing the sound channel into left and right input channel signals; applying the HRTF filters and acoustic crosstalk cancellations filters to the left and right channel signals to generate output left and right channel signals; and modulating the left and right output channel signal frequencies onto an ultrasonic carrier.</p>
