- xWMA is a container format for compressed audio data developed by Microsoft, based on Windows Media Audio (WMA) compression but with a simplified header structure optimized for streaming and playback via the XAudio2 API. It is primarily used in Xbox and Windows game development to store sound effects and music efficiently.
- 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.
