摘要： Systems and methods for adjusting audio levels in a plurality of audio signals are disclosed. One or more input signals containing one or more audio signals are depacketized. The audio signals are analyzed to determine if audio levels of the signals correspond to a desired audio level for at least some of the signals. The audio levels of signals that do not correspond are adjusted. Packets that do not require adjustment and the resulting adjusted packets are combined to form one or more output signals corresponding to the one or more input signals.

摘要： Embodiments are directed towards providing speech enhancement of audio signals from a target source and noise reduction of audio signals from a noise source. A coherence between a first audio signal from a first microphone and a second audio signal from a second microphone may be determined. A first gain function may be determined based on real components of a coherence function, wherein the real components include coefficients based on the previously determined coherence. A second gain function may be determined based on imaginary components of the coherence function. And a third gain function may be determined based on a relationship between a real component of the coherence function and a threshold range. An enhanced audio signal may be generated by applying a combination of the first gain function, the second gain function, and the third gain function to the first audio signal.
