The emergence of cellular telephony in the 1980s [4] propelled research in speech coding to new levels; as a result, a series of sophisticated narrowband vocoder algorithms began finding their way into products and telephony standards [5, 6].

Summary,e discussed, including an overview of the human auditory system and a discussion on existing psychoacoustic models. Finally, Bandwidth extension using spline fitting was discussed in Chapter 4, along with its advantages and drawbacks.作者: 乞丐 時(shí)間: 2025-3-23 14:36 作者: orient 時(shí)間: 2025-3-23 20:44
Marktschaffung und Marktsicherung psychoacoustic model is the Perceptual Weighting Filter (PWF). The PWF places the quantization noise in areas of large signal energy so that it is masked by the signal. More thorough auditory models have also become parts of standardized audio compression algorithms, e.g., ISO/IEC MPEG-1 layer 3 [46], DTS [49], and Dolby AC-3 [50].作者: 單獨(dú) 時(shí)間: 2025-3-23 23:52 作者: ARENA 時(shí)間: 2025-3-24 05:16

Principles of Bandwidth Extension,one of two categories, bandwidth extension based on explicit high-band generation and bandwidth extension based on the source/filter model. Explicit high-band generation uses speech spectral translation or speech spectral folding followed by frequency scaling of the generated band. Extension algorit作者: consent 時(shí)間: 2025-3-24 17:05
Psychoacoustics,ear are used to obtain a simplified model that enables a reduction in the information rate without affecting the perceptual quality of the audio. These models generally include the absolute threshold of hearing, critical band frequency analysis, and the masking properties of tones and noise. Audio c作者: Leisureliness 時(shí)間: 2025-3-24 21:26
Bandwidth Extension Using Spline Fitting,hich in turn places a limit on the naturalness and intelligibility of speech [1]. 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作者: Conserve 時(shí)間: 2025-3-25 02:26
Summary, with applicable extensions. Bandwidth extension techniques were first introduced in Chapter 2. 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.
