    摘要： An apparatus configured to: identify a POI in an audio scene, wherein one or more input audio signals represent the audio scene and at least one further input audio signal represents at least part of the audio scene, wherein the POI comprises a portion of the audio scene to be replaced during rendering using reconstructed audio parameters; generate, from the at least one further input audio signal, one or more complementary audio parameters that represent the POI in the audio scene; process the one or more input audio signals to obtain input audio parameters so as to enable replacement of the POI using the one or more complementary audio parameters; and combine the one or more complementary audio parameters with the input audio parameters, to create reconstructed audio parameters, so as to replace the POI in the audio scene at least partially using the one or more complementary audio parameters.

    摘要： A method and apparatus for simulating reverberation in rendering systems. A decoder/renderer may determine how to simulate reverberation with reference to audio scene description format file information or other bitstream information regarding the virtual scene geometry, and/or a lookup table. Late reverberation may be generated based on reverberator parameters derived from the virtual scene geometry, including the lengths of delay lines, attenuation filter coefficients, and diffuse-to-direct ratio characteristics, using a feedback delay network. Early reverberation may be generated based on determining what potential reflecting elements in a virtual scene geometry are reflecting planes; this may involve the simulation of ray reflection, potentially through beam tracing.

    摘要： An apparatus for audio signal rendering, the apparatus including at least one processor configured to: receive at least one microphone audio signal captured by at least one microphone within a capture environment; receive at least one projection audio signal, wherein the at least one projection audio signal is a room-impulse-response filtered at least one microphone audio signal within the capture environment; receive at least one residual audio signal, wherein the at least one residual audio signal is a result of removing the at least one projection audio signal from at least one audio signal captured by a microphone array within the capture environment; and generate at least two volumetric audio signals based on the at least one microphone audio signal, the at least one projection audio signal and the at least one residual audio signal.
