1. A system for processing an audio signal, comprising:
a circuitry configured to:
generate a mid component and a side component from a left channel and a right channel of the audio signal;
convert the mid component and the side component to a frequency domain;
generate a hyper mid component by removing spectral energy of the side component from spectral energy of the mid component by subtracting a magnitude of the side component in the frequency domain from a magnitude of the mid component in the frequency domain;
filter the hyper mid component; and
generate a left output channel and a right output channel using the filtered hyper mid component.
