IDirectSound3DBuffer8::SetConeOutsideVolume

The SetConeOutsideVolume method sets the volume of the sound outside the outside angle of the sound projection cone.

Syntax

HRESULT SetConeOutsideVolume(
  LONG lConeOutsideVolume, 
  DWORD dwApply 
);

Parameters

lConeOutsideVolume

Cone outside volume, in hundredths of a decibel.

dwApply

Value that specifies when the setting should be applied. This value must be one of the those shown in the following table.

Value Description
DS3D_DEFERRED Settings are not applied until the application calls the IDirectSound3DListener8::CommitDeferredSettings method. This allows the application to change several settings and generate a single recalculation.
DS3D_IMMEDIATE Settings are applied immediately, causing the system to recalculate the 3-D coordinates for all 3-D sound buffers.

Return Values

If the method succeeds, the return value is DS_OK.

If the method fails, the return value may be DSERR_INVALIDPARAM.

Remarks

Volume levels are represented by attenuation. Allowable values are between DSBVOLUME_MAX (no attenuation) and DSBVOLUME_MIN (silence). The default value is DS3D_DEFAULTCONEOUTSIDEVOLUME (no attenuation). These values are defined in Dsound.h. DirectSound does not support amplification.

Requirements

  Header: Declared in dsound.h.
