AMR (Adaptive Multi-Rate) is an audio format optimized for speech encoding, widely used in mobile phone recordings, VoIP calls, and narrowband audio transmission. AMR supports multi-format conversion via FFmpeg, providing efficient compression and good voice quality, suitable for mobile communications and voice recording.
How to open and play an AMR file?
AMR files can be opened and played using various tools. The most popular choices include [VLC](https://www.videolan.org/), [Audacity](https://www.audacityteam.org/), and [FFmpeg](https://ffmpeg.org/). These tools support not only AMR files but also a wide range of other audio formats. On Windows and macOS systems, you can also use built-in media players to play AMR files. On Linux systems, the `ffplay` command-line tool (part of FFmpeg) can be used to play AMR files. Regardless of the tool you choose, the process is straightforward: simply double-click the file or right-click and select 'Open'. If you need to convert an AMR file to another format, FFmpeg provides powerful command-line tools, such as `ffmpeg -i input.amr output.mp3`.
