Abstract: A method for separating sound sources includes digitizing acoustic signals from a plurality of sources with a plurality of microphone arrays, wherein each of microphone arrays includes one or more microphones, wherein at least one of the microphone arrays may be asynchronous to another one of the microphone arrays or may be moving with respect to another one of the microphone arrays. Spatial parameters are estimated of the digitized acoustic signals. The method includes estimating time-varying source spectra for the sources from the digitized acoustic signals as a function of the digitized acoustic signals and data received from at least one other microphone array. Source signals are estimated for one or more of the sources by filtering the digitized acoustic data digitized at the respective microphone array using the spatial parameters of the digitized acoustic data and the time-varying source spectra from all or a subset of the microphone arrays.

Abstract: A listening system includes one or more remote signal sources that generate one or more electronic signals, which correspond to sound in an ambient environment. A first ear microphone detects a first combination of audio signals including ambient sound and one or more propagated audio signals, corresponding to the one or more electronic signals, received at a first ear of a listener. The system includes first ear playback device and a processing device to apply a first set of audio filters including an audio filter to process a respective electronic signal of the one or more electronic signals with a first error signal, which is based on an output of the first ear microphone, to generate a first output signal to the first ear playback device, wherein acoustic cue components of the first output signal match corresponding acoustic cue components of the first combination of audio signals.

Abstract: A listening system includes a first microphone device and a second microphone device that generate a first electronic signal and a second electronic signal corresponding to sound within audio detection range. Control logic of the first microphone device detects a crosstalk audio signal from a direction of the second microphone device that matches the second electronic signal. The first electronic signal includes a mixture that includes the crosstalk audio signal. An ear playback device is associated with the second microphone device. A processing device receives the first electronic signal and the second electronic signal, removes the second electronic signal from the first electronic signal to generate a cleansed first electronic signal, and processes the cleansed first electronic signal to integrate the cleansed first electronic signal into an output signal to the ear playback device.
