The following C++ code example shows the creation of a class that inherits fromCBaseAudioProcessingObject. For an actual implementation of this concept, follow instructions in theAudio Processing Objects Driver Samplesection to go to the Swap sample, and then refer to theSwapapo.hfile. ...
This topic introduces a set of new Windows 11 APIs for Audio Processing Objects (APOs) that are shipped with an audio driver.Windows allows third-party audio hardware manufacturers to include custom host-based digital signal processing effects. These effects are packaged as user-mode Audio P...
This diagram illustrates a DSP equipped system that implements effects in hardware. In this scenario, a Proxy APO should be created to inform the apps of the effects that are implemented in hardware. Windows Audio Processing Objects Hardware Offloaded Audio Driver Implementation ...
Using Audio Processing Objects Before discussing the internals of an APO class, let me show you how to apply the effects to XAudio2 voices. The SimpleEffectDemo project in the downloadable code for this column allows you to load a file from your Windows 8 music library and...
APO 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 tech...

A very common type of audio processing involves amplifying or attenuating certain ranges of frequencies in the audio spectrum, thus altering the harmonic composition of the sound. This is a tool known as a filter. In analog signal processing, filters are circuits; in digital signal processing, th...
提交缓冲区时分配给XAUDIO2_BUFFER结构的pContext成员的上下文指针。 返回值 无 备注 在OnBufferEnd回调后,可以安全地释放与pBufferContext关联的缓冲区的音频内存。 pBufferContext是最初由XAUDIO2_BUFFER结构的pContext成员提供的上下文指针,可以是 NULL。
混合并处理音频流。 有关音频引擎如何使用缓冲区传输音频的更多信息,请参见理解WaveRT 端口驱动器(Understanding the WaveRT Port Driver). 加载音频处理对象(APO),它们是和硬件相关的音频信号处理插件。 有关APO的更多信息,请参见Windows音频处理对象(Windows Audio Processing Objects). ...
The other blocks represent various points where some form of host based audio processing happens (sample rate conversion, mixing, effects). Host based processing modules are also referred to asAudio Processing Objects, or APOs. The above link has more details on the meaning of the other acronyms...
