The signal processing apparatus includes a main microphone that is provided so as to be readily influenced by movement of air outside the signal processing apparatus, a sub microphone that is provided so as to be hardly influenced by movement of air outside the signal processing apparatus, a determiner that determines, based on a strength of a main speech signal output from the main microphone, whether the main speech signal includes a predetermined amount of wind noise, and a selector that receives the main speech signal and a sub speech signal output from the sub microphone, executes, if it is determined that the main speech signal includes the predetermined amount of wind noise, selection processing for outputting the sub speech signal, and executes, if it is determined that the main speech signal includes no predetermined amount of wind noise, selection processing for outputting the main speech signal.

In accordance with an embodiment, described herein is a system and method for use of crowdsourced microphone or other information with a digital media content environment. A user may bring their media device with media application to a venue/performance, for example a theater, or a music concert, or other event which the user desires to attend. A microphone and/or other hardware components of the media device can be used to indicate a presence of the media device. The system can also, or alternatively, utilize an interaction information by the media device or the user thereof with other systems or environments. The media application can be configured so that, upon determining that the media device is present within a particular venue or attending a particular performance, the media server can enable one or more venue-aware media application features, to provide various types of functionalities that improve the user experience.

A distributed microphones signal server includes a network interface circuit that communicates with mobile terminals and a plurality of microphones that are geographically distributed. The server receives an audio request message containing a location of the mobile terminal, and selects a microphone from among the plurality of microphones responsive to the location of the mobile terminal. The server obtains an audio stream from the selected microphone, and communicates the audio stream to the mobile terminal. Related methods by a distributed microphones signal server are disclosed. Related computer program products and methods by a mobile terminal are disclosed.

The embodiments of the present application provide an earphone abnormality processing method, an earphone, a system, and a storage medium. In the embodiments of the present application, an abnormal state self-detection function is added to an earphone of an existing dual-microphone, and when the earphone is in a self-detection state, acquiring a sound signal picked up from a specified sound source by a primary microphone and a secondary microphone; and determining the type of abnormal state of the earphone according to a frequency response curve of the sound signal picked up by the primary microphone and the secondary microphone, and further performing abnormality processing on the earphone by using a processing manner adapted to the abnormal state of the earphone, thereby solving the difficulty in the prior art of being unable to process the sound pickup abnormality of an earphone, and improving the usage performance of an earphone and also facilitating the prolonging of the service life of the earphone.

Systems, methods, devices and non-transitory, computer-readable storage mediums are disclosed for location-tracking wireless devices. In an embodiment, a method performed by an electronic device comprises: playing, or initiating the playing of, a sound through a loudspeaker of an accessory device via a communication link. The sound is played at a specified frequency that utilizes a frequency response of the loudspeaker (or loudspeaker plus speaker enclosure). The sound is received through two or more microphones of the electronic device and filtered by one or more filters. The one or more filters are configured to pass the sound at or around the specified frequency and to reduce masking of the sound by ambient noise. The filtered sound is associated with direction data generated from sensor data provided by one or more inertial sensors of the electronic device. In another embodiment, the specified frequency is higher than the maximum human hearing range.

A terminal device according to an embodiment includes: a microphone; a communication unit that performs communication via a network; a first sensor that obtains depth information; a first face detecting unit that detects a face and the distance to the face based on the depth information; and a processor. When a communication program, which is meant for making the processor perform transmission and reception of messages including voice messages and which has a sound input mode for enabling collection of sounds using the microphone and transmission of voice messages based on the collected sounds, is executed, and when a message is received by the communication unit under the control of the communication program being executed; the processor performs first-type face detection using the first face detecting unit and controls turning ON and turning OFF the sound input mode according to the result of the first-type face detection.

A position detection method may include obtaining voice signals during a voice call by at least two voice collecting devices; obtaining position energy information of the voice signals; and identifying a position of the terminal device relative to a user during the voice call, from predefined positions based on the position energy information.
