DIRECTIONAL AUDIO CAPTURE
First Claim
1. A method for improving performance of a directional audio capture system, the method comprising:
- correlating phase plots of at least two audio inputs;
generating, based on the correlation, estimates of salience at different directional angles to localize at least one direction associated with at least one source of a sound;
determining cues based on the estimates of salience; and
providing the cues to the directional audio capture system.

Abstract
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.
