AMR files are a compressed audio file format whose variable compression rates make it ideally suited to the telecommunications industry, where calls and voicemails need to be transmitted and stored using a bandwidth-efficient format.

The sound is compressed using a variable-rate compression format that automatically adjusts based on the complexity of the area being compressed. As this is best suited to voice recordings, it is not a good choice for general music compression where quality is important.

There are certain specialized audio software programs that can open and process AMR files. We also have a selection of tools to convert AMR files to other formats, such as MP3.

Extension	MP3
Full Name	MPEG-2 Audio Layer III

MP3 files are a well-known file format for the storage and playback of music and digital audio. The MP3 format has been around for a long time and has become a standard format for music. Despite newer formats arriving, such as AAC, MP3 still remains the primary choice for digital music playback.

It's highly efficient compression methods allow what would otherwise be very large audio data to be compressed down to a fraction of its size with little noticeable difference in quality. The quality, or bit rate, can be specified from 96KB/s (low quality) to 320KB/s (high quality). Naturally, the higher the bit rate, the larger the final MP3 file.

MP3 files are synonymous with digital music and are therefore supported by all major audio and music editing and playback software. Major operating systems and platforms often have built-in support for the playback of MP3 files.
