An electronic device comprising: a microphone array including at least three microphones; and at least one processor configured to: identify a kind of an application that is executed; activate one or more of the microphones in the array based on each microphone's respective position within the electronic device and the type of the application; and capture audio using the activated microphones.

Electronic device including a microphone array

An electronic device according to various embodiments of the present invention may comprise: a gyro sensor for sensing rotation of an electronic device; a memory for storing a plurality of head related transfer functions corresponding to a plurality of directions; and a processor configured to generate a stereo signal by applying, to an audio signal, a first head related transfer function corresponding to a first direction, generate a stereo signal by applying, to the audio signal, a second head related transfer function corresponding to a third direction symmetric to a second direction with reference to the first direction when the electronic device rotates from the first direction to the second direction, and generate a stereo signal by applying the first head related transfer function to the audio signal when a pre-designated time elapses after the electronic device rotates from the first direction to the second direction.

Electronic device and audio output method for electronic device

An electronic device includes a first microphone that receives a sound generated for a specific time period, from the outside, a second microphone, which is disposed at a location spaced apart from the first microphone and which receives the sound, an audio converter comprising audio converting circuitry, and a processor electrically connected with the first microphone, the second microphone, and the audio converter. The processor is configured to convert the sound obtained from the first microphone, into a first signal and to convert the sound obtained from the second microphone, into a second signal, using the audio converter, and to determine the sound, which is generated for the specific time period, as a voice or a noise based on a frequency-related correlation between the first signal and the second signal.

Electronic device and method for classifying voice and noise

The present invention relates to a frequency control apparatus for a television and a video cassette tape recorder, and more particularly to an automatic frequency control method wherein a frequency value of a voltage controlled oscillator is increased or decreased and stored by determining whether an oscillator is in a range capable of operating a phase locked loop when an oscillation frequency of the voltage controlled oscillator of the phase locked loop is not synchronized with the intermediate frequency when a frequency is automatically controlled by comparing phases and frequencies of the phase locked loop and the intermediate frequency.

Automatic frequency control method

An apparatus and a method for controlling video/audio modes in a video/audio outputting apparatus is provided, in which the audio mode is automatically set in relation to the video mode selected by the user. A judgment is made whether an inputted working command code is a video mode code or an audio mode code. If the working command code thus judged is a video mode code, then it is judged whether it is a custom mode, a standard mode, a movie mode, a dynamic mode or a mild mode. Then a value is set to the video mode code thus judged, and at the same time, a value is set to the audio mode. Meanwhile, if the working command code thus judged is a an audio mode code, then it is judged as to whether it is a custom mode, a standard mode, a movie mode, a music mode or a soft mode. Then a value is set to the audio mode code thus judged. Therefore, according to the invention, when a user watches pictures and listens to sounds and only selects the video mode, the video signals are processed according to the selected video mode, while at the same time the audio signals are automatically processed in an audio mode corresponding to the selected video mode.

Method for controlling video/audio modes in video/audio outputting

A method for removing the background noise during reception of weak electric field intensity signals. If the electric field intensity of television broadcast signals received by a main picture receiving section is weak, a PIP (picture in picture) function is released, and the release is displayed to notify it to the user. The electric field intensity of the received television broadcast signals is determined in accordance with the AGC signals of the television broadcast signals which are received by a main picture receiving section. If the electric field intensity is strong, the amplification gain of an LNA is adjusted to a low level, and a PIP function is executed or released, depending upon the user's selection of the PIP function. If the electric field intensity is weak, the amplification gain of an LNA is adjusted to a high level, and a determination is made as to whether the PIP function is being executed. If the PIP function is being executed, the PIP function is released, and the release is displayed in the form of an OSD (on screen display) to notify the release to the user. Therefore, in the present invention, when the electric field intensity of the television broadcast signals of the main picture receiving section is weak, the PIP picture receiving section is disabled, so that the PIP picture receiving section would not generate the spurious radiation, thereby upgrading the picture quality on the screen.
