Abstract
An audio system provides for crosstalk processing and crosstalk compensation processing of an audio signal. The crosstalk processing may include crosstalk cancellation processing or crosstalk simulation processing. A crosstalk processed signal is generated by applying the crosstalk processing to a side channel of the left and right channels, with a mid channel of the left and right channels bypassing the crosstalk processing. The crosstalk processed signal and the mid channel that bypasses crosstalk processing is used to generate a left output channel and a right output channel. In some embodiments, a crosstalk compensated signal is generated by applying crosstalk compensation processing to the side channel. The crosstalk compensated signal adjusts for spectral defects caused by the crosstalk processing. The crosstalk processing and crosstalk compensation processing may be applied in different orders. The left and right output channels are generated using the crosstalk processed signal and the crosstalk compensated signal.
