Can someone explain to me how FFmpeg seems to be the only open-source software to do even just basic functionality with audio.

I was looking at getting the sound wave graph for a piece of audio a while ago, and not only was FFmpeg the only option I found to be able to do it, it was amazingly fast and also free.

What ever happened to Facebook's (or was it Netflix?) technology to create a new unit of time measurement to help align audio and video files? I believe it was called a "flick"...
