Abstract

See full text

Comfort noise, such as can be used in voice communications can be generated using methods in the frequency domain and/or in the time domain. In various embodiments, a comfort noise spectrum can be generated in the frequency domain as the product of a background noise sample and a random noise sample. In other embodiments, the comfort noise can be generated directly in the time domain as the convolution of a background noise sample and a random noise sample.
