1. A method for performing a sound quality operation in a call, comprising:
receiving a first input signal into at least a first microphone array in a first environment, the input signal including background noise of the first environment, wherein the first microphone array incudes at least one pattern;
generating an anti-noise signal based on the first input signal;
receiving a second input signal into at least a second microphone array in the first environment, the second input signal comprising speech of a first user in the first environment;
enhancing the speech of the second input signal to generate an enhanced speech signal, wherein enhancing the speech is performed independently of generating the anti-noise signal; and
mixing the anti-noise signal and the enhanced speech signal to produce an output signal, wherein the output signal is transmitted to a second environment, which is remote from the first environment, over a network and is output by speakers in the second environment and is heard by a second user in the second environment, wherein the output signal in the second environment is mixed with a second anti-noise signal configured to cancel noise in the second environment determined from a first microphone array in the second environment to improve audio heard by the second user in the second environment.
