OFF-AXIS CROSS-TALK CANCELLATION EVALUATION OF 2-CHANNEL AND 3-CHANNEL OPSODIS SOUND BARS
Diana Morgan, T TAKEUCHI, Keith Holland · 2023
Optimal Source Distribution (OPSODIS) theory enables binaural cross-talk cancellation (CTC) without significant losses in dynamic range and audio quality, associated with alternative forms of transaural systems. Two types of sound-bars, a 2-channel OPSODIS and a 3-channel OPSODIS, have been developed and have proven to offer good binaural reproduction for a central, on-axis listener. This paper aims to evaluate their ability to offer CTC for second and third listeners in off-axis positions, within a realistic home listening environment.
