What is Linear predictive coding?
'''Linear predictive coding''' (LPC) is a method of [[digital signal processing]]. It is mainly used for compressing audio signals, and for [[speech recognition]]. Commonly a simplified [[Mathematical model|model]] of the human [[vocal tract]] is used. This model allows [[speech synthesis]]. This makes it possible to describe the model using less data than is used for [[Pulse-code modulation]]. Very often, an extra parameter is used to describe the difference between the original signal, and the signal calculated through the model. [[Category:Digital signal processing]]
