Popis:	Ambisonics requires high orders with many channels for high spatial accuracy, which makes real-time convolution of many HOA (high order ambisonics) sources computationally challenging. We have developed a technique to process an ambisonic impulse response to isolate the direct and early components and spatialize them with vector-based amplitude panning and using simple 2nd order ambisonics to present the diffuse late energy. This hybrid approach results in sharp imaging of the auditory scene while only requiring 14 channels of convolution per source.
