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.

What is a M4A file?
M4A stands for MPEG-4 Audio and is a popular audio format used for storing compressed audio files. Unlike MP3, M4A files often use AAC encoding, which provides better sound quality at similar file sizes. It was developed by Apple and is widely used in iTunes and iOS devices.
M4A files are typically used for music and podcasts, offering high efficiency and compatibility with modern players. Since they don't support digital rights management (DRM), they are preferred for unrestricted distribution of audio content.
How to open M4A files
M4A files can be opened with iTunes, QuickTime, VLC Media Player, and most smartphone music apps. They’re fully supported on macOS, iOS, and many Windows players.
