AMR Adaptive Multi-Rate

AMR file format uses many coding techniques, the ACELP (Algebraic Code Excited Linear Prediction) algorithm one of the best technique; designed for compressing human spoken audio in a more efficient way. The AMR was set as the standard voice or speech codec by 3GPP in 1999.

AC3 Audio Codec 3

AC3 files are binary in nature and based on the Modified Discrete Cosine Transform (MDCT) which is a lossy compression algorithm. Dolby Laboratories used the MDCT algorithm along with perceptual coding principles to develop the AC-3 audio format. This led to the release of the AC-3 format as the Dolby Digital standard in 1991.
