| Abstract: | This paper describes the low-complexity 14 kHz audio coding algorithm which has been recently standardized by ITU-T as Recommendation G.722.1 Annex C (“G.722.1C”). The algorithm is an extension to ITU-T Recommendation G.722.1 and doubles the G.722.1 algorithm to permit 14 kHz audio bandwidth using a 32 kHz audio sample rate, at 24, 32, and 48 kbit/s. The G.722.1C codec features very high audio quality and extremely low computational complexity compared to other state-of-the-art audio coding algorithms. This codec is suitable for use in video conferencing and teleconferencing, and Internet streaming applications. Subjective test results from the Characterization Phase of G.722.1C are also presented in the paper. | ||
