 Linear predictive coding

Linear Predictive Coding (LPC) is a powerful technique commonly used in speech processing and audio signal analysis. It is a method for representing the spectral envelope of a digital signal (often speech) by estimating the properties of a filter that can predict the current sample based on past samples. ### Key Concepts of LPC: 1. **Prediction Model**: LPC assumes that a current sample of a signal can be predicted as a linear combination of its previous samples.
