摘要： There is provided a device and a method of operating the device for determining whether the device is immersed in a fluid. An acceleration signal for the device is acquired (302) and a pressure within the device is detected (304). It is determined whether the device is immersed in a fluid based on a comparison of the acquired acceleration signal with the detected pressure (306).

摘要： A noise suppressor comprises a first (401) and a second transformer (403) for generating a first and second frequency domain signal from a frequency transform of a first and second microphone signal. A gain unit (405, 407, 409) determines time frequency tile gains in response to a difference measure for magnitude time frequency tile values of the first frequency domain signal and magnitude time frequency tile values of the second frequency domain signal. A scaler (411) generates a third frequency domain signal by scaling time frequency tile values of the first frequency domain signal by the time frequency tile gains; and the resulting signal is converted to the time domain by a third transformer (413). A designator (405, 407, 415) designates time frequency tiles of the first frequency domain signal as speech tiles or noise tiles; and the gain unit (409) determines the gains in response to the designation of the time frequency tiles as speech tiles or noise tiles.

摘要： An apparatus comprises a receiver (203) which receives a microphone signal from a microphone (201) where the microphone signal comprises a test signal component corresponding to an audio test signal. A divider (215) divides the microphone signal into a plurality of test interval signal components, each of which corresponds to the microphone signal in a time interval. A set processor (217) generates sets of test interval signal components and a similarity processor (219) generates a similarity value for each set. An interference estimator (221) determines an interference measure for individual test interval signal components in response to the similarity values. The interference measure may be used to select signal segments that can be used to adapt an audio processing algorithm which is applied to the microphone signal, such as e.g. speech enhancement or echo cancellation. The approach may allow for a reliable interference estimate to be generated while maintaining low complexity.

摘要： An audio capture apparatus comprises a microphone array (301) and a beamformer (303) arranged to generate a beamformed audio output signal and a noise reference signal. A first and second transformer (309, 311) generates a first and second frequency domain signal from a frequency transform of the beamformed audio output signal and noise reference signal respectively. A difference processor (313) generates time frequency tile difference measures which for a given frequency is indicative of a difference between a monotonic function of a norm (magnitude) of a time frequency tile value of the first frequency domain signal and a monotonic function of a norm of a time frequency tile value of the second frequency domain signal for the first frequency. An estimator (315) generates an estimate indicative of whether the audio output signal comprises a point audio source in response to a combined difference value for time frequency tile difference measures for frequencies above a frequency threshold.

摘要： An apparatus for determining a position estimate for an audio source comprises two microphones (M1, M2) and an acoustic element (203) providing an acoustic effect to sound from sound source positions to the first microphone (M1). The acoustic effect is asymmetric with respect to an axis (201) between the microphones (M1, M2). A position circuit (305) estimates two possible positions on different sides of the axis for the sound source in response to time of arrivals at the microphones (M1, M2). An estimator (307) determines an acoustic effect measure being indicative of a degree to which an acoustic effect of the first microphone signal matches an expected characteristic of the acoustic effect for sound sources on one side of the axis (201). Another circuit (309) determines the position estimate by selecting between the two possible positions in response to the acoustic effect measure. The approach may resolve ambiguities in position determination associated with position determination based on time of arrival at two microphones.
