文章详细介绍了Windows 8及以后版本操作系统中如何利用硬件卸载音频处理技术，允许专用处理器处理任务如混音和效果应用，以减轻主要CPU的负载。该技术有助于提高音频处理效率，尤其是在计算密集型场景下。
Hardware-offloaded audio processing allows the main audio processing tasks to be performed outside the computer's main CPU.
Audio processing can be very computationally intensive. So in many scenarios, it may be beneficial to allow a dedicated processor to take care of processing tasks like, for example, mixing, and applying effects. But Windows 7 and earlier versions of Windows did not provide support for hardware-offloaded audio processing.
With Windows 8 and later operating systems, the audio driver model has been updated to provide support for hardware-offloaded audio processing, and the following sections provide information about how to develop an audio driver that can expose its ability to handle offloaded audio for processing.
