Audio Renderer (WaveOut) Filter
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
This filter uses the waveOut* API to render waveform audio. However, the DirectSound Renderer Filter provides the same functionality using DirectSound. By default, the Filter Graph Manager uses the DirectSound Renderer instead of this filter. Audio mixing is disabled in the waveOut Audio Renderer, so if you need to mix multiple audio streams during playback, use the DirectSound renderer.
This filter does not check the audio stream's subtype. The WAVEFORMAT or WAVEFORMATEX structure passed in the format contains the information needed for the connection.
This filter supports a range of sample rates that depends on the audio driver.
