Waveformkódolás
Waveformkódolás, also known as waveform coding or speech coding, is a process used in telecommunications and digital signal processing to represent the analog waveform of a signal, typically speech, in a digital format. The primary goal is to reduce the amount of data required to represent the signal while maintaining acceptable quality. This is crucial for efficient transmission and storage of audio information.
There are several categories of waveform coding techniques. One broad category is waveform coding proper, which
Another approach is model-based coding, which uses a model of the signal's generation process. For speech, this
The choice of waveform coding technique depends on factors such as desired bit rate, acceptable distortion,
