    • Some embodiments of the invention provide a method of processing audio data while creating a media presentation. The media presentation includes several audio streams. The method processes a section of a first audio stream and stores the processed section of the first audio stream. The method also processes a section of a second audio stream that overlaps with the processes section of the first audio stream. The method then processes the section of the second audio stream independently of the first audio stream. In some embodiments, the method processes the first audio stream section by applying an effect to the first audio stream section. Also, in some embodiments, the processing of the first audio stream section also entails performing a sample rate conversion on the first audio stream section.
    • 本发明的一些实施例提供了一种在创建媒体呈现的同时处理音频数据的方法。 媒体演示包括几个音频流。 该方法处理第一音频流的一部分并存储第一音频流的处理部分。 该方法还处理与第一音频流的处理部分重叠的第二音频流的一部分。 该方法然后独立于第一音频流处理第二音频流的部分。 在一些实施例中,该方法通过对第一音频流部分应用效果来处理第一音频流部分。 而且,在一些实施例中,第一音频流部分的处理也需要在第一音频流部分上执行采样率转换。

    • Methods for analyzing a list of routine identifiers to optimize processing of routines identified in the list. Some embodiments execute a set of routines in multiple passes where each pass comprises each routine in the set processing a single band of its source. The band size of the sources of the set is related to the size of a cache used during execution of the set. A band size of sources of the set is determined so that all data processed by and produced by any routine in the set can be stored to the cache while the routine processes one band of its source. Some embodiments use the list to combine two or more routines into a single routine where the list is modified accordingly. Some embodiments use the list for grouping and re-ordering routines identified in the list to send particular routines to an alternative processor for processing.
    • 用于分析例程标识符列表以优化列表中标识的例程的处理的方法。 一些实施例在多个遍中执行一组例程,其中每个遍包括集合处理其源的单个频带的每个例程。 集合的源的带宽与集合执行期间使用的高速缓存的大小有关。 确定集合的源的频带大小,使得由该集合中的任何例程处理并由其产生的所有数据可以被存储到高速缓存,而该例程处理其源的一个频带。 一些实施例使用列表将两个或更多个例程组合到单个例程中,其中列表被相应地修改。 一些实施例使用列表来分组和重新排序在列表中标识的例程以将特定例程发送到用于处理的替代处理器。
