Abstract: A method that uses a microphone array for spatially selective sound pickup during an audio-video recording session is described. An audio signal for the audio-video recording session is generated using a beamforming process from the microphone array in accordance with a sound pickup directivity pattern. Ambient sound pressure level of the audio-video recording session is monitored while generating the audio signal. The sound pickup directivity pattern of the beamforming process is automatically adjusted during the audio-video recording session as a function of the monitored ambient sound pressure level. Other embodiments are also described and claimed.

Abstract: A method in a communications device includes the following operations. During a call, a process automatically detects that the device has moved from an at-the-ear position to an away-from-the-ear position. Based on the detection, a noise suppressor that operates upon an uplink signal for the call is signaled to change its noise suppression performance. Other embodiments are also described and claimed.

Abstract: A mobile multi-function device that includes a speaker, two or more microphones, and a beamformer processor is described. The beamformer processor uses the microphones to perform beamforming operations. One of the microphones shares a receiver acoustic opening with the speaker while the other microphone uses a separate acoustic opening. The receiver acoustic opening may be an earpiece opening that is held to the ear of a user while conducting a phone call with the device and provides acoustic input and output paths for the microphone and the speaker, respectively.

Abstract: Active noise cancellation (ANC) circuitry is coupled to the input of an earpiece speaker in a portable audio device, to control the ambient acoustic noise outside of the device and that may be heard by a user of the device. A microphone is to pickup sound emitted from the earpiece speaker, as well as the ambient acoustic noise. Control circuitry deactivates the ANC in response to determining that an estimate of how much sound emitted from the earpiece speaker has been corrupted by noise indicates insufficient corruption by noise. In another embodiment, the ANC decision is in response to determining that an estimate of the ambient noise level is greater than a threshold level of an audio artifact that could be induced by the ANC. Other embodiments are also described and claimed.

Abstract: A feed forward active noise cancellation (ANC) system for use in a portable audio device has an adaptive digital filter and a reference microphone. A non-adaptive pre-shaping digital filter has an input coupled to the reference microphone and is in series with, and in front of, the adaptive filter. The pre-shaping filter is minimum phase and presents at least 2 dB more gain over a low audio frequency band than over a high audio frequency band. This may help compensate for low frequency band difficulties, and may thereby extend ANC bandwidth at the low end without a worsening impact on the high end. Other embodiments are also described and claimed.
Abstract translation: 用于便携式音频设备的前馈有源噪声消除（ANC）系统具有自适应数字滤波器和参考麦克风。 非自适应预整形数字滤波器具有耦合到参考麦克风并与自适应滤波器串联并在其前面的输入。 预成形滤波器是最小相位，并且在低音频频带上比在高音频频带上具有至少2dB的增益。 这可能有助于补偿低频带的困难，从而可以在低端扩展ANC带宽，而不会对高端产生恶化的影响。 还描述和要求保护其他实施例。
