Audio processing objects (APOs), provide customizable software based digital signal processing for Windows audio streams. This section contains the following topics. Audio Processing Object Architecture Implementing Audio Processing Objects Implementing Hardware Offloaded APO Effects ...
Audio processing objects (APOs), provide software based digital signal processing for Windows audio streams. An APO is a COM host object that contains an algorithm that is written to provide a specific Digital Signal Processing (DSP) effect. This capability is known informally as an "audio effect...
任何将音频处理对象部署到 Windows 10 计算机上的发货标签都必须具有 OS 上限,以防止驱动程序被部署到 Windows 11 计算机上。 合作伙伴还必须发布第二个相应的发货标签,OS 下限为Windows 11 21H2,该标签会将 Class=AudioProcessingObject 驱动程序包部署到相同的 HWID 和 CHID 上。

Windows从Vista开始,使用一套叫做APO(Audio processing Object)的音频框架,让用户可以编写自己的音频效果插件。比较知名的APO包括Dolby音效插件,Viper4Windows,Equalizer APO等等,都是此类东西。增强选项卡的这些选项,实际上是windows自带的APO插件。 这些自带的APO插件,包装在一个CLSID中,封装成一个DLL。一般由设备驱动厂...
Some random notes about Windows Audio Processing Objects (APOs) by Etienne Dechamps. What is an APO? APO stands for "Audio Processing Object". It is an API and framework designed by Microsoft for building pluggable audio filters (DSP). It is quite similar to VST in principle. More technicall...
guarantees that the sum never exceeds a 16-bit value. An overall volume adjustment can also be made via the mastering voice. You might also want to look into the XAudio2CreateVolumeMeter function, which lets you create an audio processing object that can help monitor volume for debugging ...

This lab provides hands-on exercises that demonstrate how to debug the Sysvad audio kernel-mode device driver.Microsoft Windows Debugger (WinDbg) is a powerful Windows-based debugging tool that you can use to perform user-mode and kernel-mode debugging. WinDbg provides source-level debugging for ...
Because encoding and compressing video and audio content requires a high percentage of a computer's processing capability, it is recommended that you run the encoder on a separate computer from the one that is running Microsoft Windows Media Services. The list of currently supported hardware and so...
