A binaural object-oriented audio decoder including a decoder device to decode and render an audio object based on head-related transfer function (HRTF) parameters. The decoder device positions an audio object in a virtual three-dimensional space. The HRTF parameters are based on elevation, azimuth, and distance parameters and correspond to the position of the audio object in the virtual three-dimensional space. The binaural object-oriented audio decoder is configured to receive the HRTF parameters that vary for the elevation and azimuth parameters only. The binaural object-oriented audio decoder further includes a distance processor for modifying the received HRTF parameters according to a received desired distance parameter. The modified HRTF parameters are used to position the audio object in the three-dimensions at the desired distance. The modification of the HRTF parameters is based on a predetermined distance parameter for the received HRTF parameters.
