Abstract:
Embodiments provide methods, apparatuses, and systems for performing crosstalk cancellation and/or generation of virtual speakers. An audio processor may include a crosstalk cancellation circuit and a linearization circuit. The linearization circuit may offset the frequency response of the crosstalk cancellation circuit to provide an overall frequency response that is flat. A virtual speaker circuit may receive an input signal associated with an output channel and pass the input signal to the output channel unmodified. The virtual speaker circuit generates a virtualization signal based on the input signal and passes the virtualization signal to another physical channel. The virtualization signal may be generated further based on an ipsilateral head-related transfer function (HRTF) and a contralateral HRTF that correspond to a virtual speaker location of a virtual speaker generated by the virtual speaker circuit. Other embodiments may be described and/or claimed.
