Abstract: A method for generating reverberant audio signals, the method including: obtaining at least one reverberation parameter associated with a first acoustic environment; obtaining at least one audio source located at at least one position outside of the first acoustic environment, the at least one audio source having an associated audio signal; generating at least one parameter for the at least one position of the at least one audio source, related to energy propagation for the at least one audio source; and generating a reverberated audio signal associated with the at least one audio source based on the at least one parameter to adjust the level of the associated audio signal.

Abstract: An apparatus for enabling audio transition between at least two acoustic environments, the apparatus including circuitry configured to: obtain information of at least a first acoustic environment associated with an audio scene, wherein the audio scene includes the first acoustic environment and a second acoustic environment; obtain a first distance threshold that at least partially defines an audio transition region that enables adaptive rendering between the first and second acoustic environments depending on a listening position within the audio scene; determine the listening position to adjust an environment characteristic of at least one of the first and second acoustic environments; and adjust the environment characteristic of at least one of the first and second acoustic environments depending on the listening position, wherein the environment characteristic is adaptively controlled within the audio scene.
