- Description
- An AMR file is an audio file saved in a compressed audio format developed by Ericsson. It is used by many 3G cell phones for voice recordings such as MMS messages. AMR files incorporate the Algebraic Code Excited Linear Prediction (ACELP) algorithm, which is designed to efficiently compress human speech audio.
- A CDDA (CD Digital Audio File) is a type of audio file extracted directly from an audio CD. This format is also known as CD-DA, which stands for Compact Disc Digital Audio. It is a standard format for audio CDs established by Philips and Sony in the Red Book specification. CDDA files represent uncompressed digital audio data in a linear PCM (Pulse Code Modulation) format.
