Abstract: With regard to the problem that sound images of all directions can not be realized perfectly by the fixed loudspeaker gain parameters, this paper proposes a design method of Ambisonic 3D sound images reconstruction based on multi-gain parameters. In this method, the spatially continuous directions of original sound sources are quantized by Spatial Localization Quantization Point（SLQP）. Then, sound images of quantized directions are reproduced by the corresponding gain parameters. The simulation results of reconstruction for Auro-10 configuration prove that the reproduced sound localization performance of the proposed method outperforms the conventional method with the fixed gain parameters.
