摘要： Method of improving voice quality using a wireless headset with untethered earbuds starts by receiving first acoustic signal from first microphone included in first untethered earbud and receiving second acoustic signal from second microphone included in second untethered earbud. First inertial sensor output is received from first inertial sensor included in first earbud and second inertial sensor output is received from second inertial sensor included in second earbud. First earbud processes first noise/wind level captured by first microphone, first acoustic signal and first inertial sensor output and second earbud processes second noise/wind level captured by second microphone, second acoustic signal, and second inertial sensor output. First and second noise/wind levels and first and second inertial sensor outputs are communicated between the earbuds. First earbud transmits first acoustic signal and first inertial sensor output when first noise and wind level is lower than second noise/wind level. Other embodiments are described.

摘要： An acoustic system includes first one or mole acoustic elements designed and arranged in a first manner to facilitate generation of a first signal that includes mostly undesired audio, substantially void of desired audio, in response to a presence of the desired audio and the undesired audio. Second one or more acoustic elements are designed and arranged in a second complementary manner to facilitate generation of a second signal that includes both the desired and the undesired audio, in response to the presence of the desired audio and the undesired audio. A signal extraction component receives the first signal and the second signal. The signal extraction component further includes an inhibit component. The inhibit component is coupled to the first signal and the second signal. A delay element is coupled to a path of the second signal. The delay element introduces a deterministic delay to the second signal. A value of the deterministic delay is selected to model reverberation of the environment that the system is used in. The first signal is input to the adaptive filter and an output of the inhibit component is in communication with the adaptive filter to control adaptive filtering. An output of the adaptive filter is a first input to an adder and the output of the delay element is a second input to the adder. The adder subtracts the first input from the second input to create an output, which is the desired audio.

摘要： The present invention discloses a speech enhancement method and device for mobile phones. By the method and device provided by the present invention, the mobile phone holding state of a user is detected when the user is talking on the phone, so that different denoising solutions will be employed according to the state of the user in holding the mobile phone. When the user holds the mobile phone normally, a solution integrating multi-microphone denoising and single-microphone denoising will be employed to effectively suppress both the steady noise and the non-steady noise; and when the user holds the mobile phone abnormally, a solution of single-microphone denoising will be employed only to suppress the steady noise. The distortion of speech by multi-microphone denoising is avoided, and the speech quality is ensured.

摘要： A method of distinguishing sound sources includes the step of transforming data, collected by at least two transducers which each react to a characteristic of an acoustic wave, into signals for each transducer location. The transducers are separated by a distance of less than about 70 mm or greater than about 90 mm. The signals are separated into a plurality of frequency bands for each transducer location. For each band a comparison is made of the relationship of the magnitudes of the signals for the transducer locations with a threshold value. A relative gain change is caused between those frequency bands whose magnitude relationship falls on one side of the threshold value and those frequency bands whose magnitude relationship falls on the other side of the threshold value. As such, sound sources are discriminated from each other based on their distance from the transducers.

摘要： For an audio file that includes multiple channels of audio data, a novel device for detecting the configuration of the audio channels in the multi-channel audio file is presented. The device performs one or more algorithms to determine whether two or more channels are related. Such algorithms are used to distinguish stereo recordings from dual mono recordings. The algorithms are also used to detect any number of related channels, such as distinguishing six related channels from a set of surround sound microphones versus six unrelated channels (e.g., mono or a mixture of stereo and mono audio channels, etc.) These algorithms compare audio channels in pairs in order to determine which channels are sufficiently related as to constitute a stereo pair or a group.

摘要： A disclosed method includes monitoring an audio signal energy level while having a plurality of signal processing components deactivated and activating at least one signal processing component in response to a detected change in the audio signal energy level. The method may include activating and running a voice activity detector on the audio signal in response to the detected change where the voice activity detector is the at least one signal processing component. The method may further include activating and running the noise suppressor only if a noise estimator determines that noise suppression is required. The method may activate and runs a noise type classifier to determine the noise type based on information received from the noise estimator and may select a noise suppressor algorithm, from a group of available noise suppressor algorithms, where the selected noise suppressor algorithm is the most power consumption efficient.

摘要： Frequency domain signal extraction methods and apparatuses include receiving a reference signal, which contains mostly undesired audio and is substantially void of desired audio. The reference signal is decomposed into at least two reference frequency components. Filtering the at least two reference frequency components with at least two adaptive filters to form at least two filtered reference frequency components. The filtered reference frequency components are recombined in an IFFT component, to produce a filtered reference signal. A delayed signal is input to an adder. The delayed signal contains desired audio and undesired audio. The filtered reference signal is subtracted from the delayed signal to form an output signal containing desired audio. The output signal is decomposed into at least two frequency components. The filtering is adapted with the at least two frequency components. The filtering is inhibited intermittently with the at least two adaptive filters to prevent cancellation of the desired audio. In some implementations, frequency sub-bands are employed. In some implementations, an acoustic element with a Cardioid beam pattern is used to acquire the reference signal.
