Abstract (en)
[origin: WO2020221431A1] The invention relates to the technical field of 3D sound, for instance, for virtual reality (VR) applications or surround sound. The invention proposes in particular a device and a method for rendering a binaural audio signal. The device is configured to obtain a direct component of the audio signal and a diffuse component and a Direction of Arrival (DoA) from a plurality of audio channels of the audio signal. Further, the device is configured to determine a head-related transfer function (HRTF) according to the DoA. Finally, the device is configured to filter the direct component based on the HRTF to obtain a modified direct component, and to generate the binaural audio signal based on the diffuse component and the modified direct component.
