I wanted to record a talk this week so I took my MacBook Pro laptop with me to the auditorium where the talk was being held. I normally use the QuickTime Player to record audio in such cases. But this time when I attempted to use the QuickTime Player, it wouldn't actually start recording. The presenters had started talking when I attempted to begin recording their presentation, so I opted to install Sound eXchange (SoX), which provides a command-line interface (CLI) for recording and editing audio on a variety of operating systems, including Microsoft Windows, Linux, and OS X. Since I had previously installed Homebrew on OS X on the system, I opened a Terminal window and used it to install SoX.
