本文档集成了许多不同类型的音频编码:自然声音与合成声音、低比特率传输与高质量传输、语音与音乐、复杂配乐与简单配乐，以及传统内容与交互式和虚拟现实内容。本文档对单个复杂的编码工具进行了标准化，为音频同步、混音和下载后期制作提供了一个新颖、灵活的框架。 本文档不针对单一应用程序，例如real- 时间电话或高质量音频压缩。相反，它适用于所有需要使用高级声音压缩、合成、操作或播放的应用程序。本文档指定了多个领域中最先进的编码工具。随着它定义的工具与ISO/IEC 14496系列的其余部分集成，基于对象的音频编码、交互式演示、动态音轨和其他类型的新媒体的令人兴奋的新可能性得以实现。

This document integrates many different types of audio coding: natural sound with synthetic sound, low bitrate delivery with high-quality delivery, speech with music, complex soundtracks with simple ones, and traditional content with interactive and virtual-reality content. This document standardizes individually sophisticated coding tools to provide a novel, flexible framework for audio synchronization, mixing, and downloaded post-production. This document does not target a single application such as real-time telephony or high-quality audio compression. Rather, it applies to every application requiring the use of advanced sound compression, synthesis, manipulation, or playback. This document specifies the state-of-the-art coding tools in several domains. As the tools it defines are integrated with the rest of the ISO/IEC 14496 series, exciting new possibilities for object-based audio coding, interactive presentation, dynamic soundtracks, and other sorts of new media, are enabled.
