Abstract
Embodiments herein are primarily described in the context of a system, a method, and a non-transitory computer readable medium for producing a sound with enhanced spatial detectability and a crosstalk simulation. The audio processing system receives a left and right input channel of an audio input signal, and performs an audio processing to generate an output audio signal. The system generates left and right spatially enhanced signals by gain adjusting side subband components and mid subband components of the left and right input channels. The audio processing system generates left and right crosstalk channels such as by applying a filter and time delay to the left and right input channels, and mixes the spatially enhanced channels with the crosstalk channels. In some embodiments, the system includes high/low frequency enhancement channels and passthrough channels derived from the input channels, which can be mixed with the output audio signal.
