OK, I can confirm that ffmpeg is installable with homebrew, and that it will convert.
Here's the quick overview: 1.) Install homebrew. There are several web pages that can guide on this task. Here's just one: https://brew.sh/ 2.) Use it to install ffmpeg at the terminal: brew install ffmpeg 3.) Use a command to extract your audio into a format you can use in Amadeus. Here's an example that I keep in an executable script under /usr/local/bin that provides me a 24-bit wav file. It could just as easily be 16-bit. <begin code> #!/bin/bash #Use ffmpeg to extract 24bit to audio.wav #One argument is input file ffmpeg -i "$1" -acodec pcm_s24le -ac 2 audio.wav <end code> The above should leave an audio.wav file in your current working directory. Rename or further transform as needed. If you want 16 bit instead of 24, just change that value in the operational line above. Good luck!
