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 reduced crosstalk interference. The audio processing system receives an input audio signal, and performs an audio processing on the input audio signal to generate an output audio signal. In one aspect of the disclosed embodiments, the audio processing system divides the input audio signal into different frequency bands, and enhances a spatial component of the input audio signal with respect to a nonspatial component of the input audio signal for each frequency band.
