MFAudioMixDirect Method (MFFrameClass)
audio offset for source
a frame from which the mix will be implemented
audio offset for a  mix
maximal number of audio samples for a mix
start gain in dB
end gain in dB
indicates whether symmetric gain will be used for both audio data ("1") or not ("0")
Directly mixes audio data (audio data of source frame and of the mixed frame should have equal frequency)
