What is an AMR file?
AMR is a speech codec designed for mobile phone calls. Older phones saved voice recordings and call recordings as .amr files at very low bitrates.
AMR is mainly used for phone voice recordings and call recordings. It plays on some Android phones and VLC; most computers and iPhones cannot play AMR.
