IAMDirectSound interface (amaudio.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IAMDirectSound
interface specifies which window has focus for controlling DirectSound audio playback. DirectShow provides limited support for this interface:
- The DirectSound Renderer implements the GetFocusWindow and SetFocusWindow methods. It does not implement the other methods on the interface.
- The Audio Renderer (WaveOut) exposes the interface but does not implement any of its methods.
The IAMDirectSound interface inherits from the IUnknown interface. IAMDirectSound also has these types of members:
