At the early stages of speech coding research, algorithms were primarily targeted for military communications and encryption applications that focused primarily on low bit rate, narrowband representations of speech [1]. As digital communications started gaining ground in telephony appl

Explicit high-band generation uses speech spectral translation or speech spectral folding followed by frequency scaling of the generated band. Extension algorit

This is most problematic for sounds whose energy is spread over the entire audible spectrum. For example, unvoiced sounds such as “s” and “f” are often difficult to discriminate with a narrowband representation. In Fig

Explicit high-band generation was discussed as well as generation based on the source-filter model. Both envelope estimation and excitation signal extension were covered. In Chapter 3, psychoacoustics wer
