摘要:
The invention relates to an apparatus for sound reproduction of a sound information signal having spatial components, the apparatus includes:sound input means adapted to input the sound information signal;headtracking means for tracking a current head orientation of a listener listening to the sound information signal via sound emission sources and to produce a corresponding head orientation signal;sound information rotation means connected to the sound input means and the headtracking means and adapted to rotate said sound information signal to a substantially opposite degree to the degree of orientation of said current head orientation of the listener to produce a rotated sound information signal; andsound conversion means connected to the sound information rotation means for converting the rotated sound information signal to corresponding sound emission signals for outputting by the sound emission sources such that the spatial components of the sound information signal are substantially maintained in the presence of movement of the orientation of head of the listener.
