Patent ID: 8682679

Claim:
A binaural object-oriented audio decoder comprising: a decoder device configured to decode and render an audio object based on head-related transfer function (HRTF) parameters, said decoder device being further configured to position the audio object in a virtual three-dimensional space, said HRTF parameters being based on an elevation parameter, an azimuth parameter, and a distance parameter corresponding to a position of the audio object in the virtual three-dimensional space; and a distance processor configured to receive the HRTF parameters and a desired distance parameter, said received HRTF parameters varying for the elevation parameter and the azimuth parameter only, wherein the distance parameter is fixed as a predetermined distance parameter, wherein the distance processor is further configured to modify the received HRTF parameters according to the received desired distance parameter, said modified HRTF parameters being used to position the audio object in three-dimensions at a perceived desired distance, wherein the modification of the HRTF parameters is based on the predetermined distance parameter for said received head-related function parameters, wherein the HRTF parameters comprise a phase difference between an ipsilateral ear and a contra lateral ear, and a plurality of parameters including at least a level parameter for the ipsilateral ear and a level parameter for the contra lateral ear, said plurality of parameters determining the perceived position of the audio object, and wherein the distance processor is further configured to decrease the plurality of parameters of the HRTF parameters with an increase of the distance parameter corresponding to the audio object.
