What is a AMR file?
AMR stands for Adaptive Multi-Rate audio codec. Originally developed for speech compression in mobile devices, AMR is optimized for human voice and is widely used in GSM and VoLTE calls. It balances audio quality and file size, even in low-bandwidth environments.
While AMR isn’t suitable for high-fidelity music, it plays a key role in mobile communications. Many older phones and voice recorders save audio in this format, making it useful for call recordings and voicemail storage.
How to open AMR files
AMR files can be opened with VLC, Audacity (with FFmpeg), and various mobile apps. They're especially common in call recording apps and VoIP systems.
To convert AMR to more compatible formats like MP3 or WAV, AnyConv provides a simple online solution.
