 Algebraic code-excited linear prediction

Algebraic Code-Excited Linear Prediction (ACELP) is a speech coding algorithm used for compressing voice signals, primarily in telecommunications. It is a popular technique for encoding speech in a way that retains quality while reducing the amount of data needed for transmission. ### Key Features of ACELP: 1. **Linear Prediction**: ACELP relies on linear predictive coding (LPC), where the speech signal is modeled as a linear combination of its past samples.
