The control circuit includes a button detection circuit, a first-in, first-out (FIFO) data buffer, a USB endpoint buffer, a mute circuit and a USB endpoint control circuit. The button detection circuit is used for detecting whether the button is triggered. The FIFO data buffer is used for storing the recorded data. The USB endpoint buffer is used for storing the recorded data. The mute circuit is used for controlling whether the recorded data is transmitted to the USB endpoint buffer according to whether the button is triggered. The USB endpoint control circuit is used for controlling whether the audio adapter outputs the recorded data according to whether the button is triggered.

Disclosed are systems and methods for automatically transitioning between communication modes of wearable audio output devices based solely on acoustic analysis. The audio output devices may operate in one of three electroacoustic modes. In the transparency mode, an audio output device may pass through the speech signal of a nearby user. In the peer-to-peer mode, the audio output device may establish a direct low-latency radio frequency (RF) link to another audio output device. In the telephony mode, the audio output device may communicate with another audio output device using networked telephony. The disclosed methods and systems perform acoustic analysis of the near-field speech signal of a local wearer of the audio output device and the far-field speech signal of a remote talker to determine the best mode for the audio output device to use and to seamlessly transition between the modes as the acoustic environment between the wearers changes.

An electronic apparatus may include: a foldable housing which includes a hinge structure that can switch the foldable housing between a folding state or an unfolding state, a first housing structure that is connected to the hinge structure and includes a first face oriented in a first direction and a second face oriented in a second direction opposite to the first direction, and a second housing structure that is connected to the hinge structure, includes a third face oriented in a third direction and a fourth face oriented in a fourth direction opposite to the third direction, and comes into contact with the first housing structure by pivoting about the hinge structure; a first display which extends from the first face to the third face and forms the first face and the third face; a second display which forms at least a portion of the fourth face; and at least one audio input device which is disposed on at least one of the second face or the fourth face.

A system configured to detect a tap event on a surface of a device using microphone audio data and motion data. Instead of using a physical sensor to detect the tap event, the device detects a tap event based on a power level difference between two or more microphones. When a power ratio exceeds a threshold, the device may detect a tap event and perform an action, such as delaying or ending an alarm. To reduce false positives caused by wind or loud noises close to the microphones, the device may confirm a tap event using motion data that indicates actual movement of the device. In some examples, the device may detect the tap event using a neural network processing the microphone data and the motion data. In addition, the device may embed the motion data within the microphone data using unused bits of the microphone data.

An aspect of the present invention relates to an active noise cancelling or an active noise gating system that applies an algorithm for reducing ambient noise. The active noise cancelling system may be used to cancel undesired background noise but for an audio signal which is desired to be heard by the user. The present invention acts as a noise gate, wherein the algorithm(s) actively senses ambient noise levels and the algorithm stored in system memory instructs the device to mute a microphone at or above certain preset noise levels. The preset levels in which the system may mute background noise may be applied by the user using a slide bar that the user may manually adjust to apply more or less noise gating

The present disclosure generally relates to managing phone calls. In some embodiments, an electronic device with a touch screen displays a phone call user interface which includes informational items associated with phone calls as well as other affordances. In some embodiments, the electronic device displays an incoming call user interface that includes selectable options that, when selected via user input, display different user interfaces.

A device includes a memory configured to store a captured audio input signal and one or more processors configured to process the captured audio input signal to determine auditory context information within the captured audio input signal. The one or more processors are configured to determine an audio quality enhancement level to be applied to the captured audio input signal based on the determined auditory context information, and perform audio quality enhancement on the captured audio input signal based on the determined audio quality enhancement level, wherein the audio quality enhancement level is dynamically adjusted during the storing of the captured audio input signal according to the determined auditory context information.
