    • A sample rate conversion system and method uses a digital signal processor (DSP) and a separate sample rate conversion circuit (SRC) to perform multiple stream conversion and mixing of different rate input audio streams. The sample rate conversion system converts data, such as multiple streams of digital audio data sampled at different rates, and performs interpolation, decimation, FIR filtering, and mixing of multiple streams of data using the separate SRC. The SRC uses two bidirectional I/O memories for alternately storing input and output data as part of a sample rate converter. When the sample rate converter writes output to one of the bidirectional memories, it has the option of summing the data with the data already stored in the same I/O memory. Therefore a separate digital signal processor can use the sample rate converter circuit to perform some of the mixing for the multiple streams.
    • 采样率转换系统和方法使用数字信号处理器(DSP)和单独采样率转换电路(SRC)来执行不同速率输入音频流的多个流转换和混频。 采样率转换系统转换数据,例如以不同速率采样的多个数字音频数据流,并使用单独的SRC进行多个数据流的插值,抽取,FIR滤波和混合。 SRC使用两个双向I / O存储器将输入和输出数据交替存储为采样率转换器的一部分。 当采样率转换器向两个双向存储器之一写入输出时,它可以选择将数据与已经存储在同一个I / O存储器中的数据相加。 因此,单独的数字信号处理器可以使用采样率转换器电路来执行多个流的一些混合。
