Spatial Audio Processing

An apparatus comprising:

• at least one processor;
• and
• at least one non-transitory memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
• identify a portion of interest 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 portion of interest 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 portion of interest in the audio scene;
• process the one or more input audio signals to obtain input audio parameters so as to enable replacement of the portion of interest 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 portion of interest in the audio scene at least partially using the one or more complementary audio parameters, wherein the reconstructed audio parameters are used, during rendering, to create a reconstructed audio scene.

A method comprising:

• identifying a portion of interest 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 portion of interest comprises a portion of the audio scene to be replaced during rendering using reconstructed audio parameters;
• generating, from the at least one further input audio signal, one or more complementary audio parameters that represent the portion of interest in the audio scene;
• processing the one or more input audio signals to obtain input audio parameters so as to enable replacement of the portion of interest using the one or more complementary audio parameters;
• and
• combining the one or more complementary audio parameters with the input audio parameters, to create reconstructed audio parameters, so as to replace the portion of interest in the audio scene at least partially using the one or more complementary audio parameters, wherein the reconstructed audio parameters are used, during rendering, to create a reconstructed audio scene.

A non-transitory computer-readable medium comprising program instructions stored thereon for performing at least the following:

• identifying a portion of interest 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 portion of interest comprises a portion of the audio scene to be replaced during rendering using reconstructed audio parameters;
• generating, from the at least one further input audio signal, one or more complementary audio parameters that represent the portion of interest in the audio scene;
• processing the one or more input audio signals to obtain input audio parameters so as to enable replacement of the portion of interest using the one or more complementary audio parameters;
• and
• combining the one or more complementary audio parameters with the input audio parameters, to create reconstructed audio parameters, so as to replace the portion of interest in the audio scene at least partially using the one or more complementary audio parameters, wherein the reconstructed audio parameters are used, during rendering, to create a reconstructed audio scene.
