ISO/IEC TR 14496-24:2008描述了MPEG-4系统（MPEG-4文件格式）和MPEG-4音频编解码器的期望的联合行为。期望MPEG-4音频编码器和解码器允许有限长度的信号被编码到文件（特别是MPEG-4文件）中，并被再次解码以获得相同的信号，经受编解码器失真。这将允许在系统实现（特别是MPEG-4系统）中以确定性的方式使用音频，可能与视频等其他媒体一起使用。最重要的是，解码后的信号将不具有任何“；额外”；在开头或#8220；缺少”；最后。

ISO/IEC TR 14496-24:2008 describes the desired joint behavior of MPEG-4 Systems (MPEG-4 File Format) and MPEG-4 Audio codecs. It is desired that MPEG-4 Audio encoders and decoders permit finite length signals to be encoded to a file (particularly MPEG-4 files) and decoded again to obtain the identical signal, subject to codec distortions. This will allow the use of audio in systems implementations (particularly MPEG-4 Systems), perhaps with other media such as video, in a deterministic fashion. Most importantly, the decoded signal will have nothing “extra” at the beginning or “missing” at the end.
