In this work, the authors evaluate a higher-order Ambisonic (HOA) renderer that compensates for reverberant characteristics of the intended listening room; this is accomplished by decoding a HOA signal to control points distributed around a boundary surrounding the listening area, then convolving the control signal with a compensation filter derived via matrix inversion of room impulse responses (RIR) from loudspeakers to control points in the frequency domain. First, a comParison is performed over renderers utilizing increasing control point density and evaluated using simulated RIRs. Then, robustness of the renderer to simulation inaccuracy is evaluated experimentally in a listening room. Metrics of reconstructed soundfield directionality and reverberation are compared to those obtained from a conventional HOA decoder, and results demonstrate an increase in source directivity, and a reduction in reverberation time for both directional and diffuse stimuli.
