摘要： Systems and techniques are provided for processing audio data. A process can include obtaining first audio data from a first microphone in a first direction, and second audio data from a second microphone in a second direction. A directional audio signal can be generated, comprising a weighted sum of an omni-directional signal corresponding to the first audio data and a bi-directional difference signal corresponding to the first audio data and the second audio data. A constructed noise reference can be generated based on a difference between the omni-directional signal and the bi-directional difference signal. Estimated noise information associated with one or more of the first microphone or the second microphone can be determined, based on the constructed noise reference.
