This application discloses a sound masking method and apparatus, and a terminal device. When the terminal device uses a receiver as an output end of an audio signal, the terminal device determines, based on the audio signal, a masking sound signal, and then transmits the masking sound signal by using a speaker. The masking sound signal is determined based on the audio signal, and a difference between a distance from the speaker to a far field and a distance from the receiver to the far field is small. Therefore, the masking sound signal can better mask a leaked sound of the receiver and prevent information leakage in a call sound.

A control device is connected with a microphone and a display device. The control device can be used to implement a microphone gain setting process. The control device includes an adjustment knob. When the adjustment knob of the control device is pressed down, the control device starts to implement the microphone gain setting process. At the same time, a message is shown on the display device to prompt that the control device starts to implement the microphone gain setting process and prompt the user to emit a sound to the microphone for a time period. Consequently, the sound is amplified by a signal gain amplifier of the control device. Then, a message is shown on the display device to prompt the user that the microphone gain setting process is completed.

An auditory wearable device management system for supporting effective use of an auditory wearable device shared by a collection of people (hereinafter abbreviated as an auditory device) is provided. An auditory wearable device management system for distributing audio information from one or more information sound sources to an auditory device worn by each wearer constituting a collection of people and acting collectively includes wearing information holding means that associates the wearer with a wearing status of the auditory device worn by the wearer as wearing information, audio information distribution control means that outputs distribution control information for designating the wearer, the wearer being a distribution destination of the audio information from each of the one or more information sound sources.

Turntable control systems are disclosed. A playback device can include an analog audio source component such as a turntable. The playback device is configured to cause playback of first audio based on analog audio signals generated by the analog audio source component. Based on an indication that analog audio signals are no longer being generated, the playback device requests, via a network interface, audio content from one or more remote computing devices. The request can include identifying related content based on the first audio. The playback device receives, via the network interface, second audio content from, and causes playback of second audio based on the second audio content.

An audio mixing device includes: a gain setting circuit configured to set first to n-th gains based on a command input from the outside, n being an integer of 2 or more; and a mixing circuit configured to output a mixing signal obtained by mixing two or more of first to n-th multiplication data obtained by respectively multiplying first to n-th audio data by the first to n-th gains.

Technology for grouping, consolidating, and pairing individual playback devices with network capability (players) to stimulate a multi-channel listening environment is disclosed. An example method includes receiving an audio signal containing a range of audio frequencies; amplifying, according to a gain parameter, the audio signal to be reproduced by at least one speaker. The example method includes automatically increasing the gain parameter to a higher gain parameter responsive to a determination that no more than a subset of the range of audio frequencies is to be reproduced by the at least one speaker. The example method includes amplifying, according to the higher gain parameter, the audio signal containing no more than the subset of the range of audio frequencies to be reproduced by the at least one speaker.

A method can include identifying an audio output device having a first audio status. In the first audio status, the audio output device can be configured to receive first audio data of at least one software application of a set of software applications of a computing device. In the first audio status, the audio output device can be configured to emit, based on the first audio data, first audio content corresponding to the at least one software application. The method can include identifying a priority software application of the computing device. The method can include assigning, in response to the identifying the priority software application, a second audio status to the audio output device. The assigning can include preventing the audio output device from emitting the first audio content. The assigning can further include configuring the audio output device to emit second audio content of the priority software application.

Disclosed is a wireless audio device, which includes at least one microphone, at least one speaker, at least one sensor, a processor, and a memory storing instructions, and the instructions that, when executed by the processor, cause the wireless audio device, while the wireless audio device outputs a sound for reducing an outside sound acquired through the at least one microphone through the at least one speaker, to identify a specified outside sound of the outside sound acquired through the at least one microphone, to output a notification sound for indicating that the specified outside sound is identified through the at least one speaker, to identify a motion of a user of the wireless audio device through the at least one sensor, in response to outputting the notification sound, and to stop the output of the sound for reducing the outside sound based on the identified motion.

A system and method for differentially locating and modifying audio sources that includes receiving multiple audio inputs from a set of distinct locations; determining a multi-dimensional audio map from the audio inputs; acquiring a set of positional audio control inputs applied to the audio map, each audio control input comprising a location and audio processing property; and generating an audio output according to the audio control inputs and the audio inputs. The audio control inputs capable of configuration through manual, automatic, computer vision analysis, and other configuration modes.
