Overview¶
Note
Some software components in this tool flow are prototypes and will be updated in Version 2 of the library. The underlying Digital Signal Processing (DSP) blocks are however fully functional. Future updates will enhance the features and flexibility of the design tool.
This application note shows a live streaming USB sound card application which can be configured in real time via a graphical user interface running on a PC. The application is uses lib_xua to create UAC 2.0 (USB Audio class) end points and also a control end point. The host application is written in python and uses pyside (a Qt6 python wrapper) to present a window to the user.
