About AMR and MP3
AMR: AMR is a speech codec made for mobile phones. Older Android and Nokia phones, call recorders and voice-memo apps save recordings as .amr files, which many computers cannot open.
MP3: MP3 is the most widely supported audio format in the world. It uses lossy compression to make music and voice files small enough to share, while keeping quality good enough for everyday listening.
