Microsoft Media Foundation和XAudio2 [英] Microsoft Media Foundation and XAudio2

问题描述

您好！

是否可以使用Microsoft Media Foundation同时使用XAudio2播放流媒体背景音频和空间3D音效？我知道XACT支持流音频，但我宁愿避免使用XACT。

Is it possible to use Microsoft Media Foundation to play streaming background audio and spatial 3D sound effects with XAudio2 at the same time? I know XACT supports streaming audio but I would rather avoid using XACT.

干杯。

推荐答案

只要两个API都没有以独占模式打开音频设备，同时使用多个音频API就没有问题。 通常，音频呈现API以共享模式打开设备。 对于媒体基础，除非您使用SPDIF流式传输，否则您将有
明确告诉音频渲染器以独占模式打开设备。 我不知道XAudio2。

As long as neither API is opening up the audio device in exclusive mode, there is no problem using more than one audio API at the same time.  Generally, audio rendering APIs open up the device in shared mode.  For media foundation, you would have to explicitly tell the audio renderer to open up the device in exclusive mode unless you are streaming using SPDIF.  I do not know about XAudio2.
