title: How to convert raw audio file to mp3 on macOS programmatically
body: <p>I have app on Mac (Osx) and iOS that record audio and creates mp3 file.
  On the iOS app I am using <a href="https://lame.sourceforge.io" rel="nofollow noreferrer">lame</a> library and which work fine.
  So I was trying to add lame library to Mac OS app and without success. I hade error that the library is build only for iOS.
  Than I tried to find version for Mac OS but, I failed to implement it <a href="https://sourceforge.net/projects/lame/files/lame/" rel="nofollow noreferrer">link</a>.</p>
