IDirectSoundCaptureFXAec8::Reset Method

[The feature associated with this page, DirectSound, is a legacy feature. It has been superseded by WASAPI and Audio Graphs. Media Casting have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Media Casting instead of DirectSound, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The IDirectSoundCaptureFXAec8::Reset method resets the effect to its initial state.

Syntax

HRESULT Reset()

Return Value

If the method succeeds, the return value is DS_OK. If the method fails, the return value may be DSERR_OUTOFMEMORY.

Important Note for Windows Vista

Existing applications that access Windows XP Acoustic Echo Cancellation (AEC) features via the DirectSound API will no longer obtain AEC when running on Windows Vista. These applications will still run, but their calls to AEC-specific DirectSound API calls will have no effect on the captured audio.

To learn how to obtain AEC in Windows Vista, See the Windows Vista AEC topics in the Windows SDK.

Applications should not reset an effect except when necessary because it has entered an incorrect state. This might be done in response to user input. An effect must not be reset arbitrarily at startup, because another application might be using the same effect.

Requirements

Header: Declared in DSound.h.

Library: Use Dsound3d.dll.
