- 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.
- The WTV (Windows Recorded TV Show) file format is used by Microsoft's Windows Media Center to store TV recordings. Introduced with Windows 7 as a successor to the earlier DVR-MS format used by Windows XP Media Center Edition, WTV files allow users to record live television broadcasts or schedule recordings directly through their computers equipped with a compatible TV tuner card. These files encapsulate both the video and audio streams, along with metadata such as broadcast information and closed captions.
