27. A device comprising:
means for determining spatial audio data based on audio signals representing sound captured by at least three microphones; and
means for determining a metric indicative of wind noise in the audio signals, the metric based on a comparison of a first value and a second value, wherein the first value corresponds to an aggregate signal based on the spatial audio data and the second value corresponds to a differential signal based on the spatial audio data, wherein the determining the spatial audio data based on the audio signals comprises determining ambisonics coefficients based on the audio signals to generate multiple ambisonics channels.
