    Abstract: Provided are an object-based three dimensional (3-D) audio service system using preset audio scenes and a method thereof. The system and the method are suggested for enabling a user to easily and conveniently watch and listen an object based 3-D audio service by eliminating inconvenience that requires a user to control each of object audio signals of sound sources. The system includes: audio input means for inputting an audio signal; preset audio scene generating means for extracting object audio signals from the audio signal inputted through the audio input means and generating more than one of 3-D audio scene information by arranging the extracted object audio signals in a 3-D space and editing features of each object; and encoding means for encoding and multiplexing the audio signal and the 3-D audio scene information for each object audio signal.

    Abstract translation: 提供了使用预设音频场景的基于对象的三维（3-D）音频服务系统及其方法。 建议使用该系统和方法，以便用户能够通过消除需要用户控制声源的每个对象音频信号的不便，来容易且方便地观看和收听基于对象的3-D音频服务。 该系统包括：用于输入音频信号的音频输入装置; 预置音频场景产生装置，用于从通过音频输入装置输入的音频信号中提取对象音频信号，并通过将提取的对象音频信号排列在3-D空间中并产生多个3-D音频场景信息，并且编辑每个 目的; 以及用于对每个对象音频信号对音频信号和3-D音频场景信息进行编码和多路复用的编码装置。

    Abstract: There is an apparatus for evaluating the audio quality of a multi-channel audio codec, including: a preprocessing unit for synthesizing binaural signals based on multi-channel audio signals transmitted through a multi-channel of a multi-channel audio reproduction system; an output variable calculator for calculating an interaural cross-correlation coefficient distortion (IACCDist) and other output variables of the binaural signals; and an artificial neural network circuit for outputting a grade of the perceived quality based on the interaural cross-correlation coefficient distortion (IACCDist) and other output variables calculated in the output variable calculator.
