Crosstalk cancellation for speaker-based spatial rendering

A method comprising:

• perceptually smoothing, by a processor, head-related transfer functions (HRTFs) corresponding to ipsilateral and contralateral transfer paths of sound emitted from first and second speakers to corresponding first and second destinations;
• inserting an inter-aural time difference in the perceptually smoothed HRTFs corresponding to the contralateral transfer paths;
• determining a regularized matrix determined from the perceptually smoothed HRTFs corresponding to the ipsilateral transfer paths and the perceptually smoothed HRTFs corresponding to the contralateral transfer paths including the inserted inter-aural time difference;
• and
• generating a crosstalk canceller by performing a time-domain inversion of the determined regularized matrix.

A non-transitory computer readable medium having stored thereon machine readable instructions, the machine readable instructions, when executed, cause a processor to:

• perceptually smooth head-related transfer functions (HRTFs) corresponding to ipsilateral and contralateral transfer paths of sound emitted from first and second speakers to corresponding first and second destinations;
• insert an inter-aural time difference in the perceptually smoothed HRTFs corresponding to the contralateral transfer paths;
• determine a time-domain matrix from the perceptually smoothed HRTFs corresponding to the ipsilateral transfer paths and the perceptually smoothed HRTFs corresponding to the contralateral transfer paths including the inserted inter-aural time difference;
• determine a regularization term to control inversion of the time-domain matrix;
• invert the time-domain matrix based on the regularization term to generate a regularized matrix;
• and
• generate a crosstalk canceller by performing a time-domain inversion of the regularized matrix.
