Abstract:
In at least one embodiment, an apparatus for providing a virtual sound effect in a listening environment is provided. The apparatus includes at least one controller and an audio playback device. The audio playback device includes the at least one controller that is programmed to receive an audio input signal from an audio input source and to apply a head related transfer function (HRTF) to the audio input signal. The at least one controller is further programmed to apply crosstalk cancellation to the audio input signal and to generate an audio output signal after applying the HRTF and the crosstalk cancellation to the audio input signal for playback by at least one loudspeaker that is invisible to a listener in the listening environment.
