Abstract: A rendering method of an object-based audio signal and an apparatus for performing the same are provided. The rendering method of an object-based audio signal includes obtaining a rendered audio signal, performing clipping prevention on the rendered audio signal using a first limiter, mixing a signal output by the first limiter using a mixer, and performing clipping prevention on the mixed signal using a second limiter.

Abstract: A method of rendering object-based audio and an electronic device performing the method are provided. The method includes identifying a bitstream, determining a reference distance of an object sound source based on the bitstream, determining a minimum distance for applying distance-dependent attenuation, based on the reference distance, and determining a gain of object-based audio included in the bitstream based on the reference distance and the minimum distance.

Abstract: Provided are an electroluminescent device, a method of manufacturing the same, and a display device including the same, the electroluminescent device including a first electron auxiliary layer, a first light emitting layer, and a first electrode disposed on a first surface of a transparent electrode; and a second electron auxiliary layer, a second light emitting layer, and a second electrode disposed on a second surface of the transparent electrode, wherein the first electron auxiliary layer and the second electron auxiliary layer each include a plurality of zinc oxide nanoparticles, a ratio (t1/t0) of a thickness (t1) of the first electron auxiliary layer to a thickness (t0) of the transparent electrode and a ratio (t2/t0) of a thickness (t2) of the second electron auxiliary layer to the thickness (t0) of the transparent electrode are each in the range of about 0.1 to about 4.0.
