摘要:
A binaural object-oriented audio decoder comprising decoding means for decoding and rendering at least one audio object based on head-related transfer function parameters is proposed. Said decoding means are being arranged for positioning an audio object in a virtual three-dimensional space. Said head-related transfer function parameters are being based on an elevation parameter, an azimuth parameter, and a distance parameter. Said parameters are corresponding to the position of the audio object in the virtual three- dimensional space. The binaural object-oriented audio decoder is configured for receiving the head-related transfer function parameters, whereby said received head-related transfer function parameters are varying for the elevation parameter and the azimuth parameter only. Said binaural object-oriented audio decoder is characterized by distance processing means for modifying the received head-related transfer function parameters according to a received desired distance parameter. Said modified head-related transfer function parameters are being used to position the audio object in the three-dimensions at the desired distance. Said modification of the head-related transfer function parameters is based on a predetermined distance parameter for said received head-related function parameters.
