Abstract: An apparatus for spatial audio signal decoding and rendering associated with a plurality of speaker nodes placed within a three-dimensional space having virtual surface arrangement comprising a plurality of virtual surfaces. The apparatus determines an azimuth angle for each virtual surface of the virtual surface set and the arrange the virtual surfaces of the virtual surface set into an order based on azimuth angles to give an ordered virtual surface set. The apparatus then associates a virtual surface of the ordered virtual surface set to a search sector and starting from the associated virtual surface for the search sector, search the ordered virtual surface set to determine a virtual surface that encloses a target panning direction.

Abstract: Examples of the disclosure relate to an apparatus (201) for determining whether one or more microphones (207) within a plurality of microphones is blocked. In examples of the disclosure correlation between at least two microphones is estimated so as to provide an indication of whether or not incoherent noise, such as wind noise (205), is present. This can be used to avoid incorrectly identifying a microphone as being blocked and so can help to maintain a higher quality level for the audio signals captured by the microphones.

Abstract: Examples of the disclosure relate to obtaining spatial metadata for use in rendering, or otherwise processing spatial audio. In examples of the disclosure a machine learning model can be used to process microphone signals, or data obtained from microphone signals, to obtain the spatial metadata. The machine learning model can be trained to enable high quality spatial metadata to be obtained from sub-optimal or low-quality microphone arrays. Examples of the disclosure include an apparatus including circuitry for: accessing a trained machine learning model; determining input data for the machine learning model based on two or more microphone signals; enabling using the machine learning model to process the input data to obtain spatial metadata; and associating the obtained spatial metadata with at least one signal based on the two or more microphone signals to enable processing of the at least one signal based on the obtained spatial metadata.

Abstract: Examples of the disclosure relate to apparatus, methods and computer programs for spatial processing audio scenes with improved intelligibility for speech or other key sounds. In examples of the disclosure at least one audio signal including two or more channels is obtained. The audio signal is processed with program code to identify at least a first portion of the audio signal wherein the first portion predominantly includes audio of interest. The first portion is processed using a first process. The second portion is processed using a second process including spatial audio processing. The first process includes no spatial audio processing or a low level of spatial audio processing compared to the second process and the second portion predominantly includes a remainder. The processed first portion and second portion can be played back using two or more loudspeakers.

Abstract: Examples of the disclosure enable spatial audio rendering in a different format to the format that is used for the spatial audio coding. In examples of the disclosure spatial audio and first spatial metadata in a first format are obtained. The first spatial metadata enables rendering of spatial audio in a first audio format. In order to enable rendering of the spatial audio in a different format the spatial metadata is converted to second spatial metadata corresponding to a second audio format. The spatial audio can then be rendered for the second format using the second spatial metadata.
