Subband spatial processing for outward-facing transaural loudspeaker systems

A non-transitory computer readable medium comprising stored instructions, wherein the stored instructions, when executed by a processor, cause the processor to:

• receive an input audio signal comprising a left channel and a right channel;
• and
• generate a left enhanced channel and a right enhanced channel by gain adjusting side subband components and mid subband components of the left and right input channels;
• apply crosstalk cancellation to the left enhanced channel and the right enhanced channel to generate an output signal including a left output channel and a right output channel;
• and
• provide the left output channel to a left speaker and the right output channel to a right speaker to generate a sound providing a plurality of crosstalk cancelled listening regions that are spaced apart, the left speaker and the right speaker addressing outward with respect to each other.

A method comprising:

• apply crosstalk cancellation to the left enhanced channel and the right enhanced channel to generate an output signal including a left output channel and a right output channel;
• and
• providing the left output channel to a left speaker and the right output channel to a right speaker to generate a sound providing a plurality of crosstalk cancelled listening regions that are spaced apart, the left speaker and the right speaker addressing outward with respect to each other.
