Abstract: Apparatus including a processor configured to: receive a spatial audio signal associated with a microphone array configured to provide spatial audio capture and at least one additional audio signal associated with an additional microphone, the at least one additional microphone signal having been delayed by a variable delay determined such that the audio signals are time aligned; receive a relative position between a first position associated with the microphone array and a second position associated with the additional microphone; generate at least two output audio channel signals by processing and mixing the spatial audio signal and the at least one additional audio signal based on the relative position between the first position and the second position such that the at least two output audio channel signals present an augmented audio scene.

Abstract: An apparatus including circuitry configured to: provide a plurality of metrics associated with multiple directions, wherein the metrics are dependent, for the respective multiple directions, on an amount of direct-sound propagated; accumulate, for the respective multiple directions, values dependent upon the metrics associated with the respective multiple directions to enable determination of sound source directions.
