1. A system, comprising:
one or more processors; and
a non-transitory computer readable medium comprising stored program code that when executed by the one or more processors, configures the one or more processors to:
separate an audio channel into a low frequency component and a high frequency component;
apply a first Hilbert Transform to the high frequency component to generate a first left leg component and a first right leg component, the first left leg component being 90 degrees out of phase with respect to the first right leg component;
apply a second Hilbert Transform to the first right leg component to generate a second left leg component and a second right leg component, the second left leg component being 90 degrees out of phase with respect to the second right leg component;
combine the first left leg component with the low frequency component to generate a left channel; and
combine the second right leg component with the low frequency component to generate a right channel.
