this the source code of audio compression standard LPC. It is coded by C.

用线性预测编码进行语音压缩 - Speech compression using Linear Predictive Coding-LPC is the oldest and the most basic of modern speech coders. Its a lossy scheme. Playback quality isn t preserved in the process but it can be used in low bit-rate systems.

LPC voice compression and decompression example

This code is for compression of images using LPC coding which is an effective algorithm for the compression of images without losing ts quality
