摘要： An image capture apparatus that is wearable on a neck of a user, comprises first to fourth microphones provided on the mount portion, and a sound processing unit. The first and second microphones are provided at positions for collecting sound on a left side of the user who is wearing the image capture apparatus. The third and fourth microphones are provided at positions for collecting sound on a right side of the user who is wearing the image capture apparatus. The sound processing unit generates a first sound signal having a directivity for the left ear of the user, based on sound signals obtained by the first and second microphones, and generates a second sound signal having a directivity for the right ear of the user, based on sound signals obtained by the third and fourth microphones.

摘要： Methods and apparatus are provided for automatically adjusting, by an audio device, the SPL of its audio output. As described herein, the SPL is adjusted based on detected ambient noise. According to aspects, audio device iteratively adjusts the SPL based on the ambient noise. According to aspects, the SPL is adjusted to be greater than the ambient noise by a threshold SPL amount. According to aspects, the audio device outputs sound in substantially a first direction and the microphone detects sound substantially outside of the first direction. The adjusted sounds are output by the audio device.

摘要： The operational amplifier disclosed includes an input stage configured to receive power from a floating supply circuit in in a low voltage range that can float according to the common mode voltage at the input. The low voltage supply facilitates the use of low voltage components that can improve the precision of the operational amplifier by lowering the offset voltage. The input stage utilizes a first gain block and a second gain block. The first gain block is configured to have a low offset voltage while the second gain h block is configured to have a high gain. Dividing these aspects over separate gain blocks improves the precision and noise performance of the operational amplifier. The operational amplifier has high gain at low frequencies and at high frequencies due to a topology that combines a low gain, high bandwidth path with a high gain, low bandwidth path at the output.

摘要： A method and system for a headset with programmable modes, where the headset comprises a beamforming microphone: sensing an ambient sound level near the headset, and configuring the headset in one of a plurality of modes by configuring a beam pattern of the beamforming microphone based on at least the sensed ambient noise level. A user of the headset may configure the headset in the one of the plurality of modes or it may be automatically configured. The beamforming microphone may comprise an array of sound sensing elements. The headset may be configured in a quiet mode when the sensed ambient sound level is below that of a desired sound source and may be configured with a wide beam pattern. The headset may be configured in a loud mode when the sensed ambient sound level is above that of a desired sound source.

摘要： An example system for playing media content with a media playback device in a vehicle can be programmed to obtain a sound measurement indicative of a sound level associated with playback of the media content by the media playback device in the vehicle. The example system also can determine a deviation in an expected sound level based upon the sound measurement. Finally, the system can modify playback of the media content by the media playback device (110) based upon the deviation.

摘要： A method, an apparatus, and logic to post-process raw gains determined by input processing to generate post-processed gains, comprising using one or both of delta gain smoothing and decision-directed gain smoothing. The delta gain smoothing comprises applying a smoothing filter to the raw gain with a smoothing factor that depends on the gain delta: the absolute value of the difference between the raw gain for the current frame and the post-processed gain for a previous frame. The decision-directed gain smoothing comprises converting the raw gain to a signal-to-noise ratio, applying a smoothing filter with a smoothing factor to the signal-to-noise ratio to calculate a smoothed signal-to-noise ratio, and converting the smoothed signal-to-noise ratio to determine the second smoothed gain, with smoothing factor possibly dependent on the gain delta.

摘要： Systems and methods for automatically adjusting device volume based on learned volume preferences are disclosed herein. A first device receives a wireless signal from a second device. A signal strength of the wireless signal is determined, and a location of the second device is determined based on the signal strength of the wireless signal. Historical volume level data for the first device is retrieved from memory. A target volume level for the first device is determined based on the location of the second device and the historical volume level data. A volume setting of the first device is automatically adjusted to the target volume level.

摘要： The technology described in this document can be embodied in a method that includes receiving an input signal captured by one or more sensors associated with an active noise reduction (ANR) headphone, and determining one or more characteristics of a first portion of the input signal. Based on the one or more characteristics of the first portion of the input signal, a gain of a variable gain amplifier (VGA) disposed in an ANR signal flow path can be adjusted, and accordingly, a set of coefficients for a tunable digital filter disposed in the ANR signal flow path can be selected. The method further includes processing a second portion of the input signal in the ANR signal flow path using the adjusted gain and selected set of coefficients to generate a second output signal for the electroacoustic transducer of the ANR headphone.
