Abstract: An apparatus comprising means configured to: obtain at least one direction parameter value for a time-frequency part of at least one audio signal (301); obtain at least one energy ratio for the time-frequency part (301), wherein each energy ratio is associated with a respective direction parameter value; generate respective at least one modified energy ratio from the at least one energy ratio for the time-frequency part (304); determine a quantization spatial resolution for encoding the at least one obtained direction parameter value based on the at least one modified energy ratio (305); and encode the obtained direction parameter values based on the quantization spatial resolution (306).

Abstract: An apparatus, method and computer program is disclosed, comprising a means for determining that a first one of a plurality of audio capture devices, which collectively contribute respective audio signals to a spatial audio signal, has entered a condition associated with not contributing to the spatial audio signal. A further means may be provided, configured responsive to said determination for causing removal of the one or more audio signals contributed by the first audio capture device from the spatial audio signal.

Abstract: A method including receiving an audio scene including at least one source captured using at least one near field microphone and at least one far field microphone. The method includes determining at least one room-impulse-response (RIR) associated with the audio scene based on the at least one near field microphone and the at least one far field microphone, accessing a predetermined scene geometry corresponding to the audio scene, and identifying a best matching geometry to the predetermined scene geometry in a scene geometry database. The method also includes performing RIR comparison based on the at least one RIR and at least one geometric RIR associated with the best matching geometry, and rendering a volumetric audio scene experience based on a result of the RIR comparison.
