官方的usb驱动库，各位朋友也可以上ST官网去下载，这个库都是用官方的开发板实现的，要放到我们的开发板上去实现要修改一些文件

懂的都懂，可以通过adobe 的audition 去掉 audio jungle 的水印 选择一段来自audiojungle.net的音频塑材，打开au，效果，降噪/恢复 声音移除，然后再也听不到那个女人的声音了

音乐播放列表,支持自动换音乐,点击音乐,可视化页面。总而言之言而总之。麻雀虽小五脏俱全

随言： 只实现了USB播放音频功能，至于USB录音和控制音量等功能，找到了相关资料，但是个人没时间往下折腾。 官方程序X-CUBE-USB-AUDIO：https://www.st.com/zh/embedded-software/x-cube-usb-audio.html 文档《UM2195 User manual USB device audio streaming Expansion Package for STM32Cube》：https://www.stmcu.org.cn/document/detail/index/id-219223 本手册与补充STM32Cube™固件库的X-CUBE-USB-AUDIO扩展包相关联，它描述了X-CUBE-USB-AUDIO固件库以及使用方法。 文档和程序要相互配合着看。

基于CubeMX生成的USB Audio Device工程，将播放设备改为录音设备，所需文件，可在我的博客中搜索相关博客，即使用方法。

这个是我用过的AMS公司的一款应用于ANC降噪方向的demo板，AS3430,资料包括原理图，FF/FB ANC测试的一些原理解释，另外包括应用手册，相关软件等

Universal Serial Bus Device Class Definition for Audio Data Formats. The intention of this document is to describe in detail all the Audio Data Formats that are supported by the Audio Device Class. This document is considered an integral part of the Audio Device Class Specification, although subsequent revisions of this document are independent of the revision evolution of the main USB Audio Specification. This is to easily accommodate the addition of new Audio Data Formats without impeding the core USB Audio Specification.
