Abstract: An audio providing apparatus and method are provided. The audio providing apparatus includes: an object renderer configured to render an object audio signal based on geometric information regarding the object audio signal; a channel renderer configured to render an audio signal having a first channel number into an audio signal having a second channel number; and a mixer configured to mix the rendered object audio signal with the audio signal having the second channel number.

Abstract: An organic light emitting diode (OLED) according to an embodiment can include an OLED panel; a printed circuit board adhered onto a rear surface of the OLED panel; and a back cover including first and second metal layers, an inorganic substance layer between the first and second metal layers, and a pocket groove in a horizontal surface on which the OLED panel is placed and corresponding to the printed circuit board, wherein the pocket groove is formed by removing the first metal layer corresponding thereto to expose the inorganic substance layer.

Abstract: An audio apparatus and a method of processing an audio signal of the audio apparatus are provided. The method includes: receiving a main audio and an interactive audio; panning the interactive audio by using position information of a user, sound source position information of the interactive audio, and speaker position information; rendering the panned interactive audio according to a space characteristic of the main audio; and mixing and outputting the rendered interactive audio and the main audio to provide the user with a more lively interactive audio.

Abstract: An audio data processing apparatus and method to reduce wind noise. The apparatus includes a wind noise detecting unit to detect a wind noise section from an input audio signal, and a signal processing unit to reduce a low-frequency band signal of the input audio signal in the detected wind noise section. The apparatus determines whether wind is present and automatically reduces wind noise based on the determined result. Accordingly, the apparatus can effectively reduce wind noise.

Abstract: A method and apparatus to eliminate noise from a plurality of channel audio signals in which surrounding noise is mixed. The method includes detecting an existence of noise in frame units by averaging a plurality of channel input signals and estimating a noise signal of a noise-detected frame, and subtracting the estimated noise signal from each of the plurality of channel input signals.

Abstract: A method and apparatus to correct erroneous audio data when reproducing the audio data in a magnetic tape audio system having a cylindrical head structure, and a digital audio signal processing system.
