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).
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.

MPEG-1 Audio Layer III or MPEG-2 Audio Layer III (MP3) is a digital, audio-coding format used to compress a sound sequence into a very small file to enable digital storage and transmission. MP3 files are the most widely-used audio file for consumers. Due to small size and acceptable quality, MP3 files are accessible to a wide audience, as well as easy to store and share.
Because MP3 files are so prevalent, most major audio playback programs support them. Simply clicking on the file will open it in iTunes or Windows Media Player, depending on your preferred platform. Users can also preview MP3 files.
Another program that can open MP3 files is VLC media player. Keep in mind that two other file types use the MP3 extension. They are Masterpoint green points data, which is obsolete; and TeslaCrypt 3.0 ransomware encrypted file, which is malware that demanded ransom in bitcoins, but is thankfully now deactivated and no longer a threat.
