IDirectSound3DBuffer8::GetMinDistance 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 It has been superseded by WASAPI and Audio Graphs.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 GetMinDistance method retrieves the minimum distance, which is the distance from the listener at which sounds in this buffer begin to be attenuated.
Syntax
HRESULT GetMinDistance(
D3DVALUE * pflMinDistance
)
Parameters
- pflMinDistance
Address of a variable that receives the minimum distance, in meters by default. D3DVALUE is defined as float.
Return Value
If the method succeeds, the return value is DS_OK. If the method fails, the return value may be DSERR_INVALIDPARAM.
Remarks
By default, the minimum distance value is DS3D_DEFAULTMINDISTANCE, defined as 1.0 (corresponding to 1.0 meter at the default distance factor of 1.0 meters per unit).
