Where AMR files come from
Older phones' voice recorders and some call-recording apps save .amr files. They are made for speech over a phone line, so they sound narrow and tinny, and many players skip them.
Do not expect more
AMR keeps only a thin slice of the voice. The MP3 is the same narrow, mono sound, just in a file everything plays: it does not get clearer. One minute came out at 0.48 MB.
