Artificial Mobile Audio Bandwidth Extension
Yong Zhang, Ruimin Hu, Ge Gao · 2006
This paper presents a novel FFT domain bandwidth extension algorithm and adapts the proposed algorithm to AMR-WB+ audio standard. The framework is given and key technologies are described in detail. It operates with low computational complexity compared to the bandwidth extension of AMR-WB+. The subjective quality test result is given showing the quality of proposed bandwidth extension combined with AMR-WB+core is comparable to that of AMR-WB+
