    Abstract: A method of operation of a device includes receiving an input signal at the device. The input signal is generated using at least one microphone. The input signal includes a first signal component having a first amount of wind turbulence noise and a second signal component having a second amount of wind turbulence noise that is greater than the first amount of wind turbulence noise. The method further includes generating, based on the input signal, an output signal at the device. The output signal includes the first signal component and a third signal component that replaces the second signal component. A first frequency response of the input signal corresponds to a second frequency response of the output signal.

    Abstract: A method of training a device specific cloud-based audio processor includes receiving sensor data captured from multiple sensors at a local device. The method also includes receiving spatial information labels computed on the local device using local configuration information. The spatial information labels are associated with the captured sensor data. Lower layers of a first neural network are trained based on the spatial information labels and sensor data. The trained lower layers are incorporated into a second, larger neural network for audio classification. The second, larger neural network may be retrained using the trained lower layers of the first neural network.

    Abstract: Techniques for processing directionally-encoded audio to account for spatial characteristics of a listener playback environment are disclosed. The directionally- encoded audio data includes spatial information indicative of one or more directions of sound sources in an audio scene. The audio data is modified based on input data identifying the spatial characteristics of the playback environment. The spatial characteristics may correspond to actual loudspeaker locations in the playback environment. The directionally-encoded audio may also be processed to permit focusing/defocusing on sound sources or particular directions in an audio scene. The disclosed techniques may allow a recorded audio scene to be more accurately reproduced at playback time, regardless of the output loudspeaker setup. Another advantage is that a user may dynamically configure audio data so that it better conforms to the user's particular loudspeaker layouts and/or the user's desired focus on particular subjects or areas in an audio scene.

    Abstract translation: 公开了用于处理定向编码的音频以考虑收听者回放环境的空间特征的技术。 定向编码的音频数据包括指示音频场景中的声源的一个或多个方向的空间信息。 基于识别回放环境的空间特性的输入数据来修改音频数据。 空间特征可以对应于播放环境中的实际扬声器位置。 定向编码的音频也可以被处理以允许对音频场景中的声源或特定方向进行聚焦/散焦。 所公开的技术可以允许在播放时间更准确地再现记录的音频场景，而与输出的扬声器设置无关。 另一个优点是，用户可以动态地配置音频数据，使得其更好地符合用户的特定扬声器布局和/或用户对音频场景中特定主体或区域的期望焦点。
