Is there an integrated system utility that will allow one to rapidly convert AMR files to MP3 in the shell on macOS?

    There isn't an internal one, but you can use ffmpeg – Allan Sep 26 '18 at 15:17

    have you tried this command? "ffmpeg -i audio1.amr -ar 22050 audio1.mp3". Works on linux but don't know about Mac. – Natsfan Sep 26 '18 at 16:00
  • @jmh seems like it should work, but I need to figure out why the right encoder is not available yet. Got this error: "Automatic encoder selection failed for output stream #0:0. Default encoder for format amr (codec amr_nb) is probably disabled. Please choose an encoder manually. Error selecting an encoder for stream 0:0" – ylluminate Sep 28 '18 at 23:48
  • @jmh's answer works for me on macOS – Brian Kung Aug 1 '19 at 13:57
