This is what happens when you transcode the same audio file 4 times with @ffmpeg AAC, vs. libfdk_aac, at 128kbps (the docs say it's better than libfdk_aac at that bitrate): https://mrcn.st/t/orig_ffmpeg_fdk_4x.wav … looping {1 bar lossless - 1 bar ffmpeg - 1 bar fdk}

This repeated transcoding is *not* a fabricated use case. In fact, I expect *5* or even *6* generations of lossy encoding for portions of an event I'm holding on Sunday (albeit the two gens I can control, at 320kbps, to minimize loss).
