IBasicAudio interface (control.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The IBasicAudio interface controls the volume and balance of the audio stream.
This interface is implemented on the Audio Renderer (WaveOut) filter and the DirectSound Renderer filter, but is exposed to applications through the Filter Graph Manager. Applications should always retrieve this interface from the Filter Graph Manager.
