What is a AMR file?
AMR is the codec built for phone calls — optimized for speech at very low bit rates, but rarely playable outside dedicated voicemail or call-recording apps.
First released in 1999 by 3GPP / Ericsson, it uses lossy compression and no transparency, which makes it best suited to old voicemails and voice recordings from feature phones and early smartphones.

Advantages of the AMR format
Extremely small for speech
