AMR Audio Format AMR Converter
An AMR file is also known as an Adaptive Multi-Rate Codec file, and this audio format was developed by 3GPP (the Third Generation Partnership Project). Its primary function is to store spoken audio, such as MMS messages and voice recordings, and it’s widely used by mobile devices for this purpose.
AMR uses Adaptive Multi-Rate encoding and various techniques, such as the ACELP (algebraic code excited linear prediction) compression algorithm and VAD (voice activity detection) technology to efficiently compress data, reducing the file size and bandwidth usage. This makes them an ideal format for mobile devices where storage space can be limited. VideoLAN VLC media player can play AMR files, as can Apple QuickTime and Windows Media Player.

M4A Audio Format M4A Converter
M4A files are an extension of the MP4 container format (MPEG-4 or Moving Picture Experts Group-4). Originally developed by Apple as a competing format to MP3, M4As are specifically used to store audio-only material such as podcasts, music, audiobooks and other auditory entertainment. You can open these files using Apple Music, VideoLAN VLC media player, Microsoft Windows Media Player and others.
M4A files are typically encoded with ALAC (Apple Lossless Audio Codec) or AAC (Advanced Audio Coding), compressing the files to produce smaller file sizes that retain high-quality sound. Due to their reduced file sizes, M4A files are a go-to format for sharing and downloading audio content, especially music downloaded from the Apple iTunes Store. You can play M4A files with most popular media players, including Apple Music, Apple Quicktime, Windows Media Player (if you add the K-Lite Codec Pack), Adobe Audition, and VLC.
