An algorithm is presented that gives improved playback performance of higher order ambisonic material on practical loudspeaker arrays. The optimizations are based on sound field reproduction theories with additional parameters to account for the compensation of loudspeaker and listener positioning constraints and numbers of listeners. Automatic calculation of loudspeaker distances is also achieved based on room dimensions and a gain calibration routine is incorporated. Results are given to quantify the resulting algorithm performance, informal listening tests were carried out, and aspects of implementation are discussed.
