| description | Systems and methods for improving performance of a directional audio capture system are provided. An example method includes correlating phase plots of at least two audio inputs, with the audio inputs being captured by at least two microphones. The method can further include generating, based on the correlation, estimates of salience at different directional angles to localize a direction of a source of sound. The method can allow providing cues to the directional audio capture system based on the estimates. The cues include attenuation levels. A rate of change of the levels of attenuation is controlled by attack and release time constants to avoid sound artifacts. The method also includes determining a mode based on an absence or presence of one or more peaks in the estimates of salience. The method also provides for configuring the directional audio capture system based on the determined mode.
提供了用于改进定向音频捕获系统的性能的系统和方法。示例方法包括使至少两个音频输入的相图相关，所述音频输入由至少两个麦克风捕获。所述方法还可包括基于相关性而生成在不同方向角下的显著性的估计以定位声源的方向。所述方法可允许基于所述估计 |
