1. A method comprising: determining, by at least a first neural network layer of a neural network of a first device, a first signal difference between a signal characteristic of a first audio signal and a signal characteristic of a second audio signal, wherein the first signal difference includes a difference in a frequency response; compressing, by at least a second neural network layer of the neural network and based on the first signal difference, the first audio signal and the second audio signal into a third audio signal; and providing, by the first device to a second device, the first audio signal and the third audio signal.
