This is my way of saying "look, here's *one* way of using the ffmpeg AAC encoder that shows it being quite inferior to libfdk_aac, and *anyone* can hear that, and I even have a valid use case for it, so please don't brush me off?" after being brushed off for subtler cases.
My *actual* "I noticed the ffmpeg aac encoder is bad again" use case that brought things up again, this time, was 256kbps MP3 -> 320kbps ffaac -> 320kbps ffaac, which is much gentler and I *expected* it to be transparent, but it wasn't. The second ffaac had quite noticeable loss.
But the last time I tried to bring loss of that level up to the person working on the AAC encoder at the time I was dismissed, so here I am saying "okay, let me do it 4 times at 128kbps to try to prove my point in a way anyone can hear".
By the way, I do not consider it acceptable to recommend the AAC encoder if it has this kind of generational loss. Transcoding is *very* common. People *should* be afraid to use it if it's going to do this to audio when transcoding. We live in a remix culture.
