I2S传输协议，介绍了它的实现原理及时序，深入浅出，非常通俗易懂，对学习音频接口很有帮助。从事音频驱动、应用开发，音频类产品开发良好的参考资料。

为了实现远程通信发射系统的音频远程发射，提出了一种嵌入式Linux下音频的本地采集并传输至远端进行回放的设计方案。该方案采用ALSA完成本地音频数据的采集，然后利用FFmpeg将其编码为适合远程传输的AAC格式数据，通过以太网基于UDP协议传输至远端；同时在远端对接收到的音频数据，利用FFmpeg和ALSA分别完成音频的解码和回放。实验结果表明，远端回放的音频信号流畅清晰，该方案执行稳定、可靠性高。

Matlab中的重复模式提取技术（REPET），用于分离音频源。 重复是产生和感知结构的基本要素。 在音频中，混合通常由重复的背景信号与变化的前景信号叠加在一起的结构组成（例如，歌手在重复的伴奏上覆盖变化的人声或与重复的背景噪声混合在一起的变化的语音信号）。 在此基础上，我们提出了重复模式提取技术（REPET），这是一种将音频混合中的重复背景与非重复前景分离开来的简单方法。 基本思想是找到混合物中的重复元素，导出潜在的重复模型，并通过将模型与混合物进行比较来提取重复背景。 与其他分离方法不同，REPET不依赖于特殊的参数化，不依赖于复杂的框架，并且不需要外部信息。 因为它仅基于重复，所以它具有简单，快速，盲目的优势，因此可以完全轻松地实现自动化。 档案： -repet.m：具有REPET方法的Matlab类。 -examples.ipynb：Jupyter笔记本中包含一些示例。 -a
