This post from the free audio converter - MiniTool Video Converter will guide you through the basics of AMR and M4A file formats and several AMR to M4A converters.
Understanding AMR and M4A Formats
Before learning the top AMR to M4A converters, first, let’s quickly review these two audio file types.
What Is an AMR File
A file with the .amr file extension is an Adaptive Muti-Rate ACELP Codec file. This file format is primarily used for storing spoken audio and is used by many 3G cell phones to save voice recordings. AMR file format can be played with various media players, such as VLC Media Player and QuickTime Player.
What Is M4A
M4A, the abbreviation of MPEG-4 Audio, is an audio format that’s often used to store songs, podcasts, and audiobooks. It uses Apple Lossless Audio Codec (ALAC) or Advanced Audio Coding Codec (AAC) to save audio data in MPEG-4 files. M4A is similar to MP4, but the former contains audio data only.
M4A is the primary audio format for Apple products. You can often find this file type in the songs downloaded from iTunes (copyrighted songs through iTunes will be saved as M4P).
