Abstract:
A method for separating audio signals based on categories is disclosed herein. The method includes receiving an audio signal; generating a plurality of filters based on the audio signal, each of the filters corresponding to one of a plurality of sound content categories; and separating the audio signal into a plurality of content-based audio signals by applying the filters to the audio signal, each of the content-based audio signals contains a content of a corresponding sound content category among the plurality of sound content categories.
Abstract:
System and method for detecting operation of a braking system (150) of a vehicle (100). A system for detecting operation (105) of a braking system (150) of a vehicle (100) comprises a microphone (120, 121, 122, 123), and an electronic controller (110), configured to receive an audio signal from the microphone (120, 121, 122, 123), wherein the audio signal is comprised of a sound caused by contact between at least one tire of the vehicle (100) and a driving surface, generate a noise characteristic from the audio signal, compare the generated noise characteristic to a known noise characteristic, and generate a notification based upon the comparison of the generated noise characteristic to the known noise characteristic.
Abstract:
An electronic device providing a smart sound mode is provided. The electronic device includes: a user command receiver; an inputter; an outputter; and a processor configured to: in response to a predetermined event occurring, provide a user interface (UI) for guiding setting of a smart sound mode; in response to the smart sound mode being selected according to a user command input through the user command receiver, individually render a first sound signal which is a common component among a plurality of channels forming the sound signal and a second sound signal which is a differential component among the plurality of channels based on whether the first sound signal comprises a voice and whether the second sound signal comprise a sound effect, mix the first and second sound signals which are rendered into a multi-channel sound signal and control the outputter to output the multi-channel sound signal.
Abstract:
A method for associating messages with media, including multiple media elements, during playing thereof, the method including sensing at least one media element currently being played by a user during playing of the media and based on the sensing of the at least one media element currently being played by a user, playing at least one message in time synchronization with playing of the at least one media element.
