Superwideband Bandwidth Extension Using Normalized MDCT Coefficients for Scalable Speech and Audio Coding
A bandwidth extension (BWE) algorithm from wideband to superwideband (SWB) is proposed for a scalable speech/audio codec that uses modified discrete cosine transform (MDCT) coefficients as spectral parameters. The superwideband is first split into several subbands that are represented as gain parame...
