Qu'est-ce qu'un fichier AMR ?
An AMR file is an audio file saved in a compressed format developed by Ericsson. It is optimized for storing spoken audio and is used by many 3G cell phones to store voice recordings, which include MMS messages. Various media players can open AMR files, including VideoLAN VLC media player and Apple QuickTime Player.
Plus d'informations
AMR files incorporate the Algebraic Code Excited Linear Prediction (ACELP) algorithm, designed to compress human speech audio efficiently. Additionally, the files may be saved in the AMR-NB (Narrowband) or AMR-WB (Wideband) format. Wideband audio supports a broader frequency range, providing better sound quality.
Comment ouvrir un fichier AMR
You can open and play an AMR file in VideoLAN VLC media player (multiplatform), Microsoft Media Player (Windows), or Apple QuickTime Player (Mac). You can also edit the audio data an AMR file contains in Audacity (multiplatform), provided you've installed Audacity's optional FFmpeg library.
