Method of comfort noise generation for speech communication

摘要

An embodiment of the invention improves upon the International Telecommunication Union's ITU-T G.729 Annex B comfort noise generation algorithm by reducing the computational complexity of the comfort noise generation algorithm. The computational complexity is reduced by reusing pre-computed random Gaussian noise samples for each non active voice frame versus calculating new random Gaussian noise samples for each non active voice frame as described by Annex B.
