Gets the voice's filter parameters.
- pParameters [out]
Pointer to an XAUDIO2_FILTER_PARAMETERS structure containing the filter information.
This method does not return a value.
GetFilterParameters will fail if the voice was not created with the XAUDIO2_VOICE_USEFILTER flag.
GetFilterParameters always returns this voice's actual current filter parameters. However, these may not match the parameters set by the most recent IXAudio2Voice::SetFilterParameters call: the actual parameters are only changed the next time the audio engine runs after the IXAudio2Voice::SetFilterParameters call (or after the corresponding IXAudio2::CommitChanges call, if IXAudio2Voice::SetFilterParameters was called with a deferred operation ID).
Note GetFilterParameters is usable only on source and submix voices and has no effect on mastering voices.
