Abstract

This contribution presents the work in 3GPP on the standardization of a new audio codec for mobile multimedia applications including packet-switched streaming (PSS), multimedia messaging (MMS) and multimedia broadcast/multicast service (MBMS). design constraints, performance requirements, test plans, selection rules were finalized first. Next, extensive subjective listening testing was conducted. The test results showed good performance for the enhanced AAC+ and for the AMR-WB+ candidates. Enhanced AAC+ and AMR-WB+ are recommended for 3GPP Rel6 mobile multimedia services PSS, MMS, and MBMS. Both fixed-point and floating-point specifications are given in 3GPP in form of a C-code for both encoder and decoder. Conformance testing methods are specified as well

关于新的音频编解码器规范

该贡献介绍了3GPP在移动多媒体应用(包括分组交换流(PSS)，多媒体消息(MMS)和多媒体广播/多播服务(MBMS))的新音频编解码器标准化方面的工作。首先确定设计约束、性能要求、测试计划、选择规则。接下来，进行了广泛的主观听力测试。实验结果表明，增强型AAC+和AMR-WB+候选体具有良好的性能。3GPP Rel6移动多媒体业务(PSS、MMS、MBMS)推荐使用增强的AAC+和AMR-WB+。在3GPP中，对于编码器和解码器，都以c代码的形式给出了定点和浮点规格。一致性测试方法也被指定
