Claim Text:
1. A method comprises: determining, by a device, a respective masking threshold for each of at least two channels of a stereophonic signal; determining an amount of noise in response to a difference between the determined respective masking threshold for each of the at least two channels of the stereophonic signal; adding the determined amount of noise to a side channel signal, wherein the side channel signal has been obtained by converting the stereophonic signal at least into a mid channel signal and the side channel signal; quantizing the mid channel signal and the side channel signal for transmission; transmitting, via a processor, at least the quantized mid channel signal and the side channel signal; decoding the quantized mid channel signal and the side channel signal; reconstructing left and right channel signals based on the decoded mid channel signal and the decoded side channel signal; and presenting the decoded left and right channel audio signals to a user via a user interface.
