Abstract
Embodiments include a method comprising generating, based on receiving audio signals from a sound source and a noise source, (i) a first input signal and (ii) a second input signal; generating, based on the first input signal and the second input signal, an average signal; operating a first phase loop by phase shifting the first input signal to generate a first intermediate signal such that a sound component in the first intermediate signal is substantially phase aligned with a sound component in the average signal; operating a second phase loop by phase shifting the second input signal to generate a second intermediate signal such that a sound component in the second intermediate signal is substantially phase aligned with the sound component in the average signal; and generating, based on the first intermediate signal and the second intermediate signal, an output audio signal that comprises audio signals from the sound source.
