Audacity 2.2.2 — Software Lavf58.27.103?

Sometimes when I export a file, suddenly the tag appears “Software: Lavf58.27.103”.

Is this implying, that Audacity is secretly a GUI wrapper of the audio editor named Lavf58.27.103? I don’t know what’s going on here.

I did some more processing in Audacity. Suddenly, this appeared:

“Software: Cycle of 5th SoundEngine 4.12”

Does that imply, that Audacity is a GUI wrapper of multiple audio editing engines???

“Lavf58.27.103” is FFmpeg.

“Cycle of 5th SoundEngine” is unrelated to Audacity.
