Abstract
A system and method provide a user-specific sound signal for each of multiple users in a room, such as a vehicle cabin, on a sound system including at least a pair of loudspeakers for each user. The head position of each user is tracked and a user-specific binaural sound signal is generated based on the tracked head position of at least one user. Crosstalk cancellation and cross-soundfield cancellation are performed on the user-specific binaural sound signal to enable a user-specific sound signal to be output on the respective loudspeaker pair for each user. In this way, different user-specific sound signals, which may include completely different audio programs, can be provided for each user in the room.
