IDirectSoundFXI3DL2Reverb8
[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 It has been superseded by WASAPI and Audio Graphs.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 IDirectSoundFXI3DL2Reverb8 interface is used to set and retrieve effect parameters on a buffer that supports I3DL2 (Interactive 3D Audio Level 2) reverberation effects.
This interface is obtained by calling GetObjectInPath on the buffer that supports the effect.
In addition to the methods inherited from IUnknown, the IDirectSoundFXI3DL2Reverb8 interface exposes the following methods.
Parameters
| Method | Description |
|---|---|
| IDirectSoundFXI3DL2Reverb8::GetAllParameters | The GetAllParameters method retrieves the I3DL2 environmental reverberation parameters of a buffer. |
| IDirectSoundFXI3DL2Reverb8::GetQuality | The GetQuality method retrieves the quality of the environmental reverberation effect. |
| IDirectSoundFXI3DL2Reverb8::SetAllParameters | The SetAllParameters method sets the I3DL2 environmental reverberation parameters of a buffer. |
| IDirectSoundFXI3DL2Reverb8::SetQuality | The SetQuality method sets the quality of the environmental reverberation effect. Higher values produce better quality at the expense of processing time. |
Presets
| Method | Description |
|---|---|
| IDirectSoundFXI3DL2Reverb8::GetPreset | The GetPreset method retrieves an identifier for standard reverberation parameters of a buffer. |
| IDirectSoundFXI3DL2Reverb8::SetPreset | The SetPreset method sets standard reverberation parameters of a buffer. |
