Zusammenfassung:	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.
