An AMR file is a compressed audio file.

This compressed audio format is designed by Ericsson and is suitable for storing call recordings and is used for voice messages, dictaphone recordings on 3G mobile devices.

Features

Thanks to the linear prediction algorithm with algebraic code (ACELP), the AMR file effectively compresses the sounds of human speech.

This file type can be saved in two formats: narrowband and wideband.

The latter is used more often because it has higher frequencies and provides better sound quality.

Conversion

You can convert AMR files to .MP3, .OGG, .FLAC formats.
