DecodeAudioDirectlyToDeviceOutputPositions()

void FSoundFieldDecoder::DecodeAudioDirectlyToDeviceOutputPositions	(	const FAmbisonicsSoundfieldBuffer &	InputData,
		const FSoundfieldSpeakerPositionalData &	OutputPositions,
		Audio::FAlignedFloatBuffer &	OutputData
	)

DecodeAudioToSevenOneAndDownmixToDevice()

void FSoundFieldDecoder::DecodeAudioToSevenOneAndDownmixToDevice	(	const FAmbisonicsSoundfieldBuffer &	InputData,
		const FSoundfieldSpeakerPositionalData &	OutputPositions,
		Audio::FAlignedFloatBuffer &	OutputData
	)

   In the future, this can be used to decode arbitrary orders of ambisonics:

if (NumAmbiChannels == 4)
{
    FirstOrderToSevenOneLoop(NumFrames, NumOutputChannels, AmbiInputBufferPtr, NumAmbiChannels, SpeakerGainsPtr, OutputBufferPtr);
}
else if (NumAmbiChannels % 4 == 0)
{

All odd-ordered ambisonics has a channel count divisible by 4, and thus can be fully vectorized. OddOrderToSevenOneLoop(NumFrames, NumOutputChannels, AmbiInputBufferPtr, NumAmbiChannels, SpeakerGainsPtr, OutputBufferPtr); } else { EvenOrderToSevenOneLoop(NumFrames, NumOutputChannels, AmbiInputBufferPtr, NumAmbiChannels, SpeakerGainsPtr, OutputBufferPtr); }
