    • Spatial information associated with an audio signal is encoded into a bitstream, which can be transmitted to a decoder or recorded to a storage media. The bitstream can include different syntax related to time, frequency and spatial domains. In some embodiments, the bitstream includes one or more data structures (e.g., frames) that contain ordered sets of slots for which parameters can be applied. The data structures can be fixed or variable. The data structure can include position information that can be used by a decoder to identify the correct slot for which a given parameter set is applied. The slot position information can be encoded with either a fixed number of bits or a variable number of bits based on the data structure type.
    • 与音频信号相关联的空间信息被编码为比特流,其可被发送到解码器或记录到存储介质。 比特流可以包括与时间,频率和空间域相关的不同语法。 在一些实施例中,比特流包括一个或多个数据结构(例如,帧),其包含有序集合的时隙,可以对其应用参数。 数据结构可以是固定的或可变的。 数据结构可以包括可由解码器使用的位置信息来识别应用给定参数集的正确时隙。 基于数据结构类型,时隙位置信息可以用固定数量的位或可变数目的位进行编码。
