Claim 14:
15. A system for producing transaural spatialized sound, comprising:
a memory configured to store parameters of a head related transfer function;
an input port configured to receive at least two audio channel signals representing acoustic emissions from spatial objects;
a spatially filter configured to generate a virtual spatial array of virtual audio signals representing spatialized audio, having a larger number of virtual audio signals than a number of channels, based on the head related transfer function and the at least two audio channel signals;
a mapper, configured to map a plurality of the virtual audio signals into a respective physical transducer signal for each of a plurality of transducer signals, wherein a number of number of virtual audio signals is greater than a number of respective physical transducer signals, the plurality of virtual audio signals being time-offset with a time delay element based on at least an estimated time difference of arrival at the ears of the listener; and
an output port configured to present the physical transducer signals.
