FormattedBuffer	FAlignedByteBuffer	For non-float situations, this buffer is used to convert RenderBuffer before pushing it to CircularBuffer.	AudioMixer.h
PopBuffer	Audio::FAlignedByteBuffer	Buffer read by the platform interface thread.	AudioMixer.h
RenderBuffer	Audio::FAlignedFloatBuffer	Buffer that we render audio to from the IAudioMixer instance associated with this output buffer.	AudioMixer.h

EAudioMixerStreamDataFormat::Type GetFormat()	Returns the format of the buffer.	AudioMixer.h
int32 GetNumSamples()	Gets the number of frames of the buffer.	AudioMixer.h
void Init ( IAudioMixer* InAudioMixer, const int32 InNumSamples, const int32 InNumBuffers, const EAudioMixerStreamDataFormat::Type InDataFormat )	Initialize the buffer with the given samples and output format.	AudioMixer.h
