The GetFrequency method retrieves the frequency, in samples per second, at which the buffer is playing.
HRESULT GetFrequency( LPDWORD pdwFrequency );
If the method succeeds, the return value is DS_OK. If the method fails, the return value may be one of the following error values:
Return code |
DSERR_CONTROLUNAVAIL |
DSERR_INVALIDPARAM |
DSERR_PRIOLEVELNEEDED |
The frequency value for software buffers is in the range of DSBFREQUENCY_MIN to DSBFREQUENCY_MAX, defined in Dsound.h. Hardware buffers can return other values.
