    摘要： A method for blind source separation based spatial filtering on an electronic device includes obtaining a first source audio signal and a second source audio signal. The method also includes applying a blind source separation filter set to the first source audio signal and to the second source audio signal to produce a spatially filtered first audio signal and a spatially filtered second audio signal. The method further includes playing the spatially filtered first audio signal over a first speaker to produce an acoustic spatially filtered first audio signal and playing the spatially filtered second audio signal over a second speaker to produce an acoustic spatially filtered second audio signal. The acoustic spatially filtered first audio signal and the acoustic spatially filtered second audio signal produce an isolated acoustic first source audio signal at a first position and an isolated acoustic second source audio signal at a second position.

    摘要： A wireless device is provided that makes use of other nearby audio transducer devices to generate a surround sound effect for a targeted user. To do this, the wireless device first ascertains whether there are any nearby external microphones and/or loudspeaker devices. An internal microphone for the wireless device and any other nearby external microphones may be used to ascertain a location of the desired/targeted user as well as the nearby loudspeaker devices. This information is then used to generate a surround sound effect for the desired/targeted user by having the wireless device steer audio signals to its internal loudspeakers and/or the nearby external loudspeaker devices.

    摘要： A method of orientation-sensitive recording control includes indicating, within a portable device and at a first time, that the portable device has a first orientation relative to a gravitational axis and, based on the indication, selecting a first pair among at least three microphone channels of the portable device. This method also includes indicating, within the portable device and at a second time that is different than the first time, that the portable device has a second orientation relative to the gravitational axis that is different than the first orientation and, based on the indication, selecting a second pair among the at least three microphone channels that is different than the first pair. In this method, each the at least three microphone channels is based on a signal produced by a corresponding one of at least three microphones of the portable device.
