MP3 revolutionized digital music distribution and became the standard format for portable media players and online music sharing.
Thanks to its balance of quality and size, MP3 remains highly relevant for casual listening, streaming, and downloading music. Nearly every media player and device supports it natively.
How to open MP3 files
MP3 files can be opened with virtually any media player: Windows Media Player, iTunes, VLC, Winamp, and countless mobile apps all support the format.

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.
