Block diagram of ART filtering: After VBAP mapping of simulated direct and reverberant signals, both components are processed through the analysis and synthesis framework of a Gammatone filterbank. For the direct sound, energy-compensation gains g_d⁽ⁱ⁾ are applied, while for the reverberant sound, cross-mixing coefficients α⁽ⁱ⁾ and β⁽ⁱ⁾, along with gains g_r⁽ⁱ⁾, are used. For each loudspeaker, the direct and reverberant signals are combined and then convolved with an audio file before playback.
