Multichannel-to-Wave Field Synthesis Upmixing Technique Based on Sound Source Separation
In this research, we propose a multichannel-to-loudspeaker array upmixing algorithm. To take advantage of a loudspeaker array, we introduce an approach based on audio source separation. During the analysis phase, multichannel signals are separated into element signals in stereo format through stereo-channel extraction. They are then separated into source signals by the Laplacian Mixture Models of the features from the stereo signals. During the synthesis phase, the sources are rendered as virtual sources through Wave Field Synthesis, or as focused sources. Subjective tests show that the proposed algorithm outperforms the comparison algorithm in terms of localization quality.
