Adaptive Multi-Rate (AMR) is a compressed audio file that is often used for speech coding. The AMR speech codec focuses on narrowband signals, which makes it ideal for voice recordings and radio. It is used regularly in Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS).

 

How to open an AMR file?

Since AMR files are often used on mobile phones, including for MMS messaging, most 3G mobile devices are able to open them. AMR also opens with VLC media player, QuickTime, RealPlayer, and Xine.

 

Other software, such as the free audio-editing software Audacity, can open AMR files. Download audacity easily at SourceForge.net. Because AMR files are heavily compressed and focused on narrowband signals, they are not suitable for music files.

Android Audio is an MP3 file encoded for Android phones and tablets. MP3 is the safest possible choice for the platform: every Android device made in the last two decades plays it, regardless of manufacturer or version, and the compression keeps file sizes small enough to store hundreds of tracks on a phone. Song title, artist, and album art travel with the file as ID3 tags.

 

How to open an Android Audio file?

Copy the file to your device over USB, Bluetooth, or a cloud service, then tap it. Android plays MP3 in Google Files, YouTube Music, or whichever music app came with the phone.

 

If a track does not show up in your music library, the media scanner may not have indexed it yet — restarting the device usually fixes this. Apps such as VLC for Android and Poweramp play files from any folder directly. The same MP3 also plays on any computer, browser, or car stereo. Our audio converter can re-encode a track for a different device or format.
